Consoles are dying.
Nintendo's IPs are largely appealling to the more casual consumer and younger consumer and therefore would be best suited to mobile.
Let's face it NSMB on tablet would sell 100m units easy.
Zelda would be similar to DS versions. Metroid in M:oM style would work fine. Pikmin and Fire Emblem would be especially well suited to mobile.
Really the only Nintendo IPs not suited to mobile would be Metroid Prime and console style Zelda but both would run brilliantly on Android (or rumoured Apple) devices with dual analog controls.
Until WiiU there was no such thing as HD Nintendo gaming so the lack of sheer horsepower in tablets/Android devices wouldn't be missed. Heck, some are already more powerful than Wii.
I know this won't be a popular opinion here, but Nintendo IPs would selling gangbusters on mobile.
