I'd much sooner expect DKC
On mobile. I think Nintendo learnt that 2D platformers sell gangbusters to an expanded audience, but not really to the Nintendo faithful. At least they're not getting a new console for it. Going forward I think you'll see more examples like Mario Run for mobile and 3D Mario for the Switch, where the more straightforward 2D games are pitched specifically at the expanded audience to get them to upgrade to the more complex experience on the Switch. So between the two I would expect Retro to work on Metroid. Or otherwise 3D dankey kang.
