I think a Fusion platform could do reasonably quite well for Nintendo, but their execution needs to be *miles* better than their sloppy Wii U/3DS launches.
Super Mario Galaxy 3, Mario Kart 9, Animal Crossing Next, IMO should all already be in development for it *now* so that they're ready or almost ready for launch by spring/summer 2016. No lazy sequels ala NSMBU either ... I'd push the dev teams to make each installment of these titles the best possible. They should have an all-purpose "Nintendo Amiibo Universe" title too ala Skylanders by 2015/16.
There should be at minimum 2 big Japanese third party games early on too ... a Monster Hunter 5, Yokai Watch 3/4, Dragon Quest XI ... that type of thing.
They should make sure they have one killer app for launch and one more killer game 2-3 months after launch to prevent the dreaded post-launch lull.
I wouldn't go crazy courting third parties, but I'd sit down with a few key third parties and have very frank, open discussions. No bullsh*t, lets make some real deals here that are win-win for both sides.
