No. that ain't gonna happen. There is no reason for Nintendo to try to confuse the market. A pro version of the Switch I'm sure would have better specs but not by like double, and not to make it so you could only play games when the OG Switch is plugged in. That sounds horrendous. A pro Switch should just deliver a premium experience, which means games that run slow don't run slow anymore, or games that would run at say 720p or 900p docked get to run in 1080p docked instead. Something like that.

I think a premium experience of the Switch would be:

More performance to make games run smoother or higher res (no splintering userbase)

Larger screen the eliminates the dead space in the current model

More disk space

more scratch resistant screen, maybe better kickstand

bluetooth so you can use wireless headphones

The above things seem like something that would be worth coming out with a premium version of the Switch for $50 more than OG Switch, and maybe even eventually eliminating the original, like 3DS did, so that Nintendo keeps the higher price point into the future, and the Lite remains the low price point, so people who want to "Switch" have to get the most expensive but better (than the original) version. Even if off the bat this new version made less profit than the original, they could market it as a better Switch as so keep the price high for longer and therefore make more profit long term.

There is no confusion if every game can work on every model. It's like saying people couldn't understand the N64 RAM expansion. Saying you need a battery pack for certain games is the simplest and cheapest "hardware upgrade" in the history of gaming. 

Definitely $199 minimum for a hypothetical Switch TV, but such a console may as well be modified and ditch the SSD storage in favor of an HDD because portability doesn't need to be considered anymore. For example, Switch TV with a 500 GB HDD and Pro Controller for $249-279.

$149? That's not hope, that's wishful thinking.

You are forgetting what makes the Switch special - it's a handheld and a console.

Most of Nintendo's big games already run @1080p60 so wouldn't need a boost

Not to mention semi decent 7200RPM mechanical hard drives can offer more performance than the cheap, slow "SSD" in the Switch currently...

Why not? (AUD will be higher of course.)

You are essentially ditching the display, battery, joycons and dock, that substantially lowers your BoM, should end up cheaper than a Switch Lite.

Obviously Nintendo doesn't consider those features to be special anymore, hence the handheld-only variant. (Which people said would never happen at one point.)

You sure about that? Like... Absolutely certain? List them.

Expansion pack was required to run 3 games, and one of those games was sold with it. And you are not saying it'll work on every model, you are saying it'll work on the new models and won't work portable in the older models. Saying you can run a game on a TV but can't in portable mode unless you have a battery pack is very confusing and would guaranteed to be highly unpopular among players. New 3DS had what 5 or less games that couldn't run on older versions, N64 had 2 games that didn't have the expansion pack bundled in that couldn't run without it. So no, not gonna happen. Terrible optics, terrible marketing, would play terrible with the userbase, and a terrible cheap idea overall.

Pretty sure nintendo has also noticed how big of a fuck up it was to not make the lite dockable. So I don't think they are too thrilled about trying something similar.

If they were to do a "Switch Pro" with better specs, the way they could get around the issue of splintered userbase is to do this

Pro Switch Specs:

393 GFLOPS undocked (which is the current Switch's docked performance)
800 GFLOPS docked (new higher performance mode for TV)

So old Switch models can't run these games, right? Well not neccessarily.

You can run these games on the older Switch models, but only the 393 GFLOP profile version of the game would run. This isn't impossible, it would just necessitate a battery pak when you are playing portably.

But this is really not a big deal, one can buy a 4500 MaH battery bank for $15, Nintendo could even offer an official one.

This way, games would run across all models, but the Pro model would be getting the better docked home performance is all.

Homebrewers on Switch are able to to get the undocked Switch to run at docked speed ... the system is fine, it doesn't overheat or anything. They're doing stuff like getting The Witcher 3 running at 60 fps undocked. It's just you lose battery life and that could be fairly easily augmented because batteries are dirt cheap and widely available.
