Which is why I expect a Switch XL instead of a Mini first. This would allow for a bigger battery, hence more battery life. Shouldn't be much bigger though (around 7 inches suffice), else it would get too heavy to play mobile. And unlike a Mini, it would still be able to Dock on the base model, just streching out a bit on the sides when doing so.

A Switch Mini would definitly enter Smartphone territory when it comes to size. Which is why I think such a Switch would be a Switch Phone. With eShop instead of Google Play store and some added productivity apps. And this one would be a pure mobile Switch with non-detachable joycons (simply too small), though you could link some Switch Joycons for movement based games.

And yeah, I think both will come in due time.

Actualy I am not handheld gamer, I thinking whats most logical. You do realise that handheld market was in most cases bigger than home console market for Nintendo, that goes for last 3 Nintendo gens.

Its not point whats kids like, its point what's more practical and to have lower price point.

Like wrote, Switch Mini/Pocket means lower price point and more practical handheld device, that basically means more offers for consumers to choose, fact is that not everyone are willing to pay $250-300 for Switch, not everyone needs TV mode and that some people want smaller and more practical Switch.

I relly dont see how fact that 3DS is worst selling portable having anything with what we talk, fact is also that 3DS will sell 5x more than Wii U, and that almost evre Nintendo handheld outsold evre Nintendo home console.

You are wrong, I dont think that Switch is "too big", but it's definitely big if you compared to all others handhelds and not most practical if you are using it like handheld only device, so I dont think that size of Switch is mistake, but its very smart to offer and Switch that's smaller and more practical for only handheld use with lower price point, same like it was smart to offer bigger 3DS. And I am sure that Nintendo will do exactly that when 3DS dies, because that's totally make sense, cheaper, smaller, more practical Switch only for handheld use that will have more affordable price point ($150-200) that will effectively replace 3DS price point on market. You need to realise that Nintendo always had lower price point and more affordable offer, they will definitely not abonde that with Switch. Even this analyst talk about smaller and cheaper version of Switch because that totally make sense and that's expected from Nintendo, they don't mention bigger more expensive version of Switch.

Actually, I believe the appeal of the hardware is mainly due to the fact you can play all Nintendo games on a single platform and without great compromises such as very limited hardware power and resolution, or unnecessary and complicated controllers.

A would argue people aren't really that much interested to play home console games on the go, or more precisely, most people may be interested on paper but are not willing to buy a console just for it. In fact, we already had a console to provide high-end console experiences on the go and it quite delivered on it's promise.

That's not to say getting some quality 3rd party support isn't important. Nintendo should focus to get key 3rd party titles that can offer something meaningfull on the system. Random PS4/XB1 ports are not likely to happen and wouldn't do much to the system anyway.

"Switch" is the brand name now, not obligatory a description of its features. It doesn't matter if some Switch models lack of some "switching features" as long as they are compatible to Switch games.

The "PlayStation Portable" wasn't stationary either.

And of course Nintendo could offer (profitable) accessories for the Switch handheld in an unibody to get the lacking features back: a handheld-fitted docking station should do the trick. The normal joy-cons and the Pro controller would be compatible and override the internal controls, so TV-mode and kickstand-mode would still be possible.

So buyers who want a compact and lighter handheld in the first place, could buy that version with lower entry costs. If they later get interested in TV-mode or motion controls, they can buy the necessary accessories to do that later (and probably pay a bit more in total, but keep the size and weight advantages for "normal" handheld gaming).

"Switch" is also only one syllable, that is a good setup for name extensions describing the different models of the platform family.

They could call the handheld version "Switch lite", "Switch mini", "Switch Pocket", "Switch XS", "Switchy" or "Switch U" (for unibody)... okay, I doubt that they use the last name ;)

A home console version they could name "Switch Home", "SwitchStation", "Switch Base" or "Switch TV".

A faster hybrid version with a bigger display (the device wouldn't necessary be bigger) and better battery life they could name "Switch Advance", "Switch Endurance", "Switch Pro", "Switch Premium" or "Switch XL".

The thing is though, the Switch's name is the main concept of the system. That's why the name works and is the main selling point. I always thought of the name 'Playstation' as a station to play, and why it works as the name of their line of systems.

I think a better example would be the Vita systems. The official name of the console version is 'Playstation TV' and not something like 'Vita Home'

Which is why attaching a core console of portable version of the Switch with that name wouldn't make sense. It's not a hybrid anymore. You're not going to be doing any 'Switch'ing on those systems. Sure, they could release accessories to make them like the original concept, but that wouldn't be the purpose of those systems anyways.

And if they made a smaller or larger version of the Switch, then that would just require more accessories, which would just make more of a mess and overall confusion. Just imagine regular joy cons, XL cons, lite cons, XL dock, lite dock. That would just be too much I feel.

They wouldn't have to make regular joy cons, XL cons and lite cons. 

An XL-Switch would have a bigger display by reducing the bezels. The height of the device would stay the same, so the normal joycons would be compatible.

The handheld-Switch would also connect to the regular joycons, either to allow motion controlled games or the joycons in the regular grip-controller for TV mode.
The Switch Pro controller would also only be in one version, compatible to all Switch models.

The only different accessory would be a fitting dock for the Switch version. And that would be even less confusing than chosing the right recharging dock for your 3DS model (even the recharging docks for the 3DS XL and new 3DS XL aren't the same because Nintendo changed the position of the power connection).

The main purpose of the Switch ain't switching games between tv-mode and handheld-mode all the time, that is only a secondary function.

The main purpose of the Switch is to be a good platform for video games and to reach as many players as possible... handheld-only gamers, tv-only gamers and people who enjoy both.

Sorry, but I'm having a hard time imagining how these different versions would look like...

And the Switch manages to reach as many people as possible by being a platform that can be played anywhere and any way.

It doesn't take THAT much imagination:

Switch Pro/XL model: the same body as the normal Switch, but with a bigger display (7.x inch) by reducing the bezels. More energy efficient SoC (Tegra X2?) to enhance either battery life (of the same battery size) or to use it for better graphics (docked mode on the go). 1080p display instead of 720p display, if they go the docked mode route.

Switch lite/mini: smaller body, less weight, controls built into the body, no HD-rumble. The same display size (6.2 inch) as the normal Switch by reducing the bezels, so no downgrade here. The battery capacity could be the same with the space gained by ditching HD rumble and the separate joycon batteries. More energy efficient SoC (Tegra X2?) to enhance battery life. If you want to play motion controlled games, you buy a pair of joycons, which override the internal controls.

So how do you play Switch games on the normal Switch if you leave the Joy Cons at home? With the Switch lite you can play any Switch games without mandatory motion controls.

Filling up only one instead of two pockets ain't better portability? Some people want to carry some other things with them (f.e. a wallet and/or a smartphone), which take some place in the second pocket.

Less weight ain't an advantage both for carrying and using the device?

Instantly being able to play instead of first reconnecting the two joy cons ain't an advantage on the go?
