It doesn't matter, the limiting factor on the main Switch unit for VR is its display. 720p is 360p per eye, at which point you might as well be sticking your face back into Virtual Boy. Not to mention: the display needs some method of displaying 90 to 120 FPS, even if that's by some form of re-projection like what PSVR relies on. Increasing the screen resolution to 1080p would cut Switch's battery life in half, if not worse, and the benefit to VR would be minimal as well. Unless you do a tri-subpixel display like PSVR, in which case we're looking at another $100 or $150 or so just for the screen you'd be getting on Switch, no hardware improvements. So yeah, I put Nintendo's chances of pursuing this at 0% to 1%.
like i said i just see them doing it to sell you more hardware, mark my words in 2 or 3 years time you will see it
it will basically be a totally new system ,maybe utilizing an X2 based chip ,you will just be able to use the old joycons and the dock with it
and it most likely will need to be teathered so battery will not be an issue ,it will be able to utilize full power for whatever processor it runs because it won't run on battery , PSVR is teathered to the PSVR processing box so battery is not an issue
and i would not rule out Nintendo also having a new dock with a built in processing unit or an add on for the current dock
pretty much the only thing that will make it a switch will be back compatibility with current switch games ,joycons and dock.
the industry is trending towards mid life cycle hardware refreshes and i certainly do not see Nintendo bucking this trend
for the very reason that so much of their business has relied on selling new hardware especially in their handheld division
if Sony can do it i do not see why Nintendo can't.
of course they are going to be selling you a bunch of new more expensive hardware to do it
i don't know why this is looked at as a downside for Nintendo , they want to sell you hardware
Sony did it a year ago so if Nintendo does it in 2 or 3 years time it will be a lot cheaper for them than it was for Sony ,having 3 or 4 more years
of new hardware generations driving prices down for the processor and screen
and of course we know Nintendo will probably use something old ,as old and as cheap as they can get away with just like 3DS running at 240
they love to make use of old hardware (also resistive touch screens are ancient and they used them in the 3DS ( not that i think a capacitive screen would not have been worse option for several reasons) )
also they might be trying to form a partnership with a display technology manufacturer like they did with nvidia for the switch processor
have a batch of custom proprietary displays commissioned like they did with the switch and it's processor
2 ways to cut costs, one is to do it like they did with the 3ds and just use old legacy hardware and two is to try and work a deal like they did with nvidia to get custom parts
but you really just never know with Nintendo , it just seems to me that those joycons are deliberately designed to be used as VR controllers
seems like there is more to their plan than just selling you a shitty tech demo as full title like they did with the ridiculously overpriced 1,2,switch
also remember that Nintendo makes the majority of it's profits off of it's dedicated base of fan boys so if they only have one hardware iteration of the switch then those fan boys only have to spend once to buy the single hardware unit
now if those same people will buy anything because it is Nintendo and fan boys were offered new models then they would certainly be opening their wallets once again
just like they did with the 3DS ,i think there is enough money to be made of these types of people for Nintendo to consider it
the fan boy who bought a launch day switch will not have to spend any more money the whole console generation
but if they were to make a couple more hardware iterations then that is more money for Nintendo
i can see it maybe being a sort of stepping stone, next iteration will be higher def screen then after that they sell you the VR base unit with extra processor
and the headset adapter
