The Problem Nobody Wants To Admit About Nintendo
Everything's Gonna Be 4K
Looking to the future, then, the general consensus seems to be that if Nintendo are to keep up with Sony and Microsoft, at least for the next couple of years until a true successor to the Switch is released (maybe even day and date with the PS6 and Xbox-Whatever), then they need to prove the rumours true and release an updated version of the Switch.
Should this so-called Switch Pro hit the market at some point in early-ish 2021, it could sport updated Joy-Cons, a bigger, brighter, 4K screen, a larger memory, and a longer battery life. Newer titles would output in native 4K, and older titles could be upscaled as close to this new resolution as possible. This is mere speculation at this point, but mid-generation hardware revisions are now an industry-standard practice, and the New 3DS is evidence of Nintendo's willingness to improve on current hardware.
Whilst an updated Switch may indeed help Nintendo to claw back ground they could well lose to their shiny new rivals, it is on the Switch's true successor that much depends. Were Nintendo to step back into sync with their two main competitors, and look to match - or even better - the technology of the day rather than leaning once more into radical control methods, they could shake off the negative image they seem to have acquired in recent years.
