I didn't think people would be as engaged in this thread as it turns out, considering the switch isn't even 2 years old yet.

GTA5 Online does not run on a 360/PS3 though that's kind of the problem. 

We don't know how demanding RE7 is, people always say this stuff like they know more than the developer. In any case, Resident Evil 2 Remake likely can't run on the current Switch. 

You have a Switch that's 2-3x the performance, which should be fairly easy to achieve by 2020 (the Tegra X1 chip will be 5 years old by then and we already have mobile chips in that range or better being sold today in Apple's A12X) and ports like that and Kingdom Hearts 3 become fairly easy for a dev. 

You don't need "most of the 3rd party games". 8-15 of the bigger IP per year is good enough. Eventually the Switch Pro will phase out the current Switch and the developer can continue to enjoy sales from their port as more and more people transition upwards and others join into the Switch ecosystem choosing the Pro model instead of the regular one. 

The main thing is internal storage actually. 32GB will eventually become as cheap as 16GB is, probably by 2020. Even 64GB will eventually be affordable, but the internal storage is the key. Increasing the Switch Pro's internal storage to 128GB should allow anyone the option of having one of the large games. It just comes down consumer choice and how they want to allocate their storage space. 

Call me insane but I'd love as with M$ that we see virtually headsets. I have to see vr as the future, the tech will improve. Eventually the tv will be replaced, what with if not vr

Wrong, GTA Online was running on PS3/360 but after GTAV launch for PS4/XB1 they focused on online just for those consoles and cut PS3/360 support, and that actually have sense. So GTA5 was running on PS3/360 in any case. Also even if Online is problem for Switch, I dont see how Switch Pro could solve that.

Yes we do know how much RE7 is demanding, point that RE7 runs at locked 1080p with very stable 60PFS on base Xbox (while Doom for instance runs at 830p with FPS that most of time is below 60) is telling us that's not demanding game and that Switch wouldnt have problem running that game (probably at least 900p/30FPS docked). RE2 maybe could run maybe couldn't, but that's different story, we still dont know how will run on XB1/PS4.

But thats huge number of games in any case that couldnt run on much higher part of Switch install base, and that's far from realistic scenario that we could have. Pro Switch is not only possible Switch revision, potential lower price point Switch is far more possible than Switch Pro, so its not like that in any time of Switch life span potential Switch Pro would only Switch revision that will be in sale. Also buy time Switch Pro could arrive, current Switch would probably have 50m+ install base, hardly that any 3rd party devs would release game that cant be played on higher number of install base of one platform. Also you need to have your expactions in check, I mean look at New 3DS compared to regular 3DS, you have just few games that couldnt run on older model, similar will be probably with "New Switch" (no Pro Switch, New will maybe have around 2x more power than current Switch), but expecting 8-15 bigger games per year that could run only on "New Switch" is IMO crazy.

Not really, you can easily expand internal memory by MicroSD card, but devs cant do nothing about currently high price of Switch carts. I agree that by time costs of Switch carts will go down, maybe even next year, but I talking about one of current biggest problems when comes to some big 3rd party games that could come to Switch, so for those games its not power problem.

If Switch Pro has 128GB on board storage, that could hold hypothetically (not saying this game would be out on Switch Pro or not, but lets assume it is):

Red Dead Revolver 2 (lets say approx 80GB, it's 85GB on XBox One) + Super Mario Odyssey + Pokemon Lets Go + Zelda: BotW + Smash Brothers Ultimate all on internal storage. That's a fair amount of games you can store internally. Could be even less if you bought those games on carts (lets say 32GB is the max size devs will use circa 2020), so RDR2 could only require say 50GB in that case. In which case you can now have Splatoon 2 + Skyrim + one other fairly reasonable sized game on there.   

That's before getting an SD Card, which are getting dirt cheap. 128GB are very affordable already and 256GB by 2020 will be cheap.

But Switch can also easily have even now more than 128GB, you can buy 128GB MicroSD for $20-30 and to have 150GB+ memory, again internal memory is not problem. Point is that some big devs want to have hole game or at least most of their game on cart, and they cant do that with 16GB carts with their games and 32GB Switch carts are currently too expansive.

You will have both a Pro model and "kids" models (cheap/smaller/whatever). Nintendo wants to sell the most hardware, the success of the PS4 Pro and XBox One X is a revenue model Nintendo will not look off of, it's too much money and it helps hardware sales too much to ignore. It also allows you to keep selling models at a premium price point which reaps higher profit margins as time goes on, which is something every business suit at Nintendo will like.. PS4/XB1 would be showing larger signs of decline without Pro/X revisions all the sales metrics say that. Just like paid online + smartphone gaming, Nintendo won't be able to ignore that money. Besides that, there are already relaible insiders on ResetEra that basically have stated a "Switch Pro" exists internally at Nintendo. 

Money talks to the new Nintendo, they're not the same company from 15 years ago, the board of directors aside from Miyamoto is completely different and the business priorities are clearly on maximizing revenue/profit, so old rules like "we don't charge for online", and "we'll never make smartphone games, and even if we did we'll never do the gacha revenue model" ... uh nope and nope. 

Switch Pro isn't out today, so the cost of a 32GB cart today is irrelevant. By 2020 that will likely be cheap, and a Switch Pro can have higher internal storage to boot (as the price of that will also be dropping as time goes on). Likely Nintendo is offering 64GB next year because the of a scale down in pricing ... 32GB will likely become as cheap as the 16GB, and 64GB will occupy the price point of the current 32GB. 32GB even for a cartridge supplier is nothing these days. Today's Nintendo won't be able to stay away from the money that premium "Pro" models bring in (Apple does it too, iPhone XS, iPad Pro, etc. etc. the big money is in the fatter profit margins you get). Of that I'm reasonably confident. 

Pro models as a concept are here to stay (not just New 3DS style unimpressive upgrades), MS and Sony are already reaping the benefits of it, it won't be long before Nintendo is too. 

Miyamotoo already covered some of this, but you can assess how demanding a game is by how is performs on real hardware.

For example, RE7 operates at 1080p and between 50-60fps on Xbox One. Wolfenstein II operates at 810p with a similar framerate, and Doom can drop to 828p or lower and the framerate into the 40s.

On PS4, RE7 is a locked 1080p/60, yet Doom can drop below that in both resolution and framerate, and Wolfenstein II wavers between 50-60fps at 1080p.

Ergo, it can be surmised that RE7 is less demanding than Doom and Wolfenstein II.

RE7 isn't really any prize anyway. The games you want are RE2 Remake and RE8. You want to have Kingdom Hearts 3 and FF7 Remake. You want to have Call of Duty series (even in Japan, this sells a lot). You want to have GTAV with online play. If a Pro model can accomodate that easily and make it so the dev doesn't have to jump through 3000 hoops to get the game running acceptably, that's probably worth doing. You don't need to have every game but you want to have some of these bigger IP. 

And we're probably at the point with chip tech where that's possible already, the Apple A12X has got to be a good 3-5x better than the current Switch processor, by 2020 a chip of that class will be a good deal cheaper. 

I still think too for OG Switch units there could be a reasonable way to offer the new higher end chip as a supplemental add-on. Nintendo patented this very concept already, and mobile chips are tiny, you could integrate one into something that's like a Switch stand. It doesn't have to be like some giant brick next to the Switch.
