This is so not how this works. Switch fans need to get it through their heads that the system will not be seeing many Xbone/PS4 ports of games that are built for hardware of that power level. At best the Switch would get "adaptations" of popular games if it became super successful to the point the third parties couldn't ignore it, like the Wii did. The Wii didn't just get those alternate versions of COD and such because of the motion controls, it got them because it was so much weaker than the 360 and PS3. Same thing here, except currently the third parties have no incentive to do that yet.
You're not making any sense whatsoever. You said we shouldn't expect AAA 3rd party ports because of power disparity, and then you said the reason why we got ports of cod Wii games was because the hardware was much weaker? Wtf You're contradicting yourself.
First of all, even though the Wii version is well over 10x weaker than 360, they were pretty great ports for the hardware limitations. Treyarch did an amazing job porting all those Wii and Wii u cod games. Besides obvious graphical differences(and cut to 30fps) Gameplay was identical with to a T,minus a few stripped content like DLC and things that weren't possible due to hardware limitations like kill cams and some kill streaks.
The main reason why we got Wii ports was because third party devs saw the Wii sell like hotcakes(motion sensing was a big thing back then also, and we got games like metroid prime 3 and other fpsers), and they did actually make profit for them. This is why support of cod games stopped after ghosts on Wii U, because they weren't making profit.
The switch is only roughly 3x weaker than the PS4 after you count newer hardware efficiency and fp16 in some situations. The bandwidth is its weakest point, but they can work around it for a but with tile based rendering. Bot to mention, its the easiest. We've already seen 3rd party ports on switch and they actually perform quite well to ps4/xbone versions. Nintendo port console to port to. But still, despite how much weaker Wii was over 360, it goes to show you that ports are indeed possible, and if devs say power is an issue as why they aren't porting the game, its mostly BS and really just about making profit.
The switch FOR SURE can get any ps4/xbone game with good performance and nearly identical fidelity, at the sacrifice of resolution(and/or framerste) and some graphical effects. Going from 720p to 1080p already takes 2.25x the GPU processing power, so expect a lot of 720p ports(with dynamic resolution) on docked mode, or 1080p with lower graphical fidelity vs ps4 base versions.
