I am considering battery draw, and where things are projecting for chips coming in 2019 - 2021. There is no way a mobile form factor device is going to play next gen games at 4K/60, but a mobile device doesn't need to. A device with a 5 - 6" screen needs to be able to run at a stable 720p, and the IQ will be excellent. On the 7nm process the AMD layout I am suggesting should be possible in the same power window as Switch right now. That will improve even more with 7nm+. I have no doubt Nvidia is capable of matching or exceeding these results.
Nintendo should be able to launch a Switch 2 in 2021, that is comfortably capable of playing 720p versions of PS5/XB4 games, while having equal or better battery life to the current Switch. I think with next gen Switch, Nintendo will implement their supplemental GPU power dock design, we have seen, which will allow them to hit 4K while docked for those that want it. I believe Switch 2 will have a Basic dock model, and a Pro dock model to reach more consumers. I don't think Nintendo has to compete directly with Sony and Microsoft in the power race, but they do need to stay current.
I think the Switch was a great rebound for Nintendo, and I am really enjoying it. There first party titles have been excellent, and it offers just enough to give Switch only owners an option to play current gen titles. Next gen, they should be in position, to have a competitive platform from all angles, so Wolfenstein 3 can be a much less compromised expereince on their platform.
The thing is though, these ports and such that the Switch has gotten in the first year and a half of its life have kept the 17m+ people who got the Switch really happy for that time period, keep in mind that it's possible gamers just had a gap in their time/pocket for the device exactly the way it is now and aren't really put off by the Sub HD graphical output of it, I know more power opens up more doors in terms of making it easier for companies to port a more complete version of a game to the system, but not since the Sega Nomad have we gotten a handheld type machine which is capable of playing these sort of full AAA titles on the go in any real capacity at all.
I just think that when it comes to options to play these games on the big screen gamers have the option to get out an X1X or a PS4P and play them at higher resolution than Switch, heck if all people wanted was the best resolution for all their games all we would see in the charts would be 100% of consoles being sold be the X1X or else no console at all since all gamers would be using an i9 with a 1080ti in it, that's not the world we live in though, the reality is that most powerful console out there now is likely to be making up 5-10% of the weekly sales of the X1 or in numbers terms around 4-8k per week in comparison to the 480k combined PS4's, Switch and standard X1 systems which sell. When you look at the numbers of what actually sells each week, that means that somewhere in the region of 1-2% of gamers (console) opt for the most powerful choice to play their games on.
I'm not contesting that you have a point with the advancement in hardware comes with the possibility for the addition of GPUs in the dock and such for those who really want that UHD experience, all I'm saying is you should look at the data we have on the sales right now and see exactly what % of the market is going out to buy that product and how many in the real world are happy to be able to fight their way out of Hell or destroy the Fuhrer on the go, even at sub hd/30fps.
(imagine being able to connect one of these to any console, the Jaguar wouldn't know what to do with it, but the tech is there to allow this sort of addition if people have the money to spend https://www.amazon.co.uk/GIGABYTE-Nvidia-Gaming-External-Graphics/dp/B076XVLWHM/ref=pd_sbs_147_1?_encoding=UTF8&pd_rd_i=B076XVLWHM&pd_rd_r=9aed9f8e-7d06-11e8-9757-4d6404bb6412&pd_rd_w=bqpaY&pd_rd_wg=wLyZx&pf_rd_i=desktop-dp-sims&pf_rd_m=A3P5ROKL5A1OLE&pf_rd_p=5179604776422437276&pf_rd_r=1AZGSGEF0NV1FT0MJAD2&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=1AZGSGEF0NV1FT0MJAD2 )
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
