Nintendo doing a Skylanders/Disney Infinity-like take using their impressive stable of characters (news story here and seemingly everywhere else) was one of my past unsolicited suggestions for helping to goose the Wii U's listless sales, but I fear that their intended implementation, which seems to involve the figures working across a range of games is too non-specific. Critically, I think they also need a triple-A Disney Infinity-like open world/mini-game title for fans to rally around and where all of the figures will work. To my mind, having that (and future sequels) in conjunction with letting the characters work in several future games (Mario Golf, Smash Bros., their platformers, etc., all immediately come to mind) would be a slam dunk. It might even help turn the Wii U's fortunes around, but even if it didn't, it could certainly point to a great plan for Nintendo's future and an all-in-one successor to both the Wii U and aging 3DS (whose sales I expect to remain fairly steady, if no longer on a growth trajectory) that could incorporate the needed technology from day one. The only major hold up for incorporating connected figures in future Nintendo titles and, even with a possible triple-A open world/mini-game showcase title, is the company's continued sluggish software release schedule, which has plagued them for many years now. This inability to iterate quickly might also be why their strategy is just to bake use of the figures into select future titles--that would clearly take less time.
At its core, a correctly implemented figurine concept would indeed be a killer business plan, but not if Nintendo continues at their current glacial release pace since this is the type of thing that needs to feed on its own momentum. In any case, we'll know more about Nintendo's intended strategy for this concept around E3 in June. Let's hope they get it right.
I do appreciate nintendo trying to stay on the floating point, but sadly for my childhood company that made my days happier, i have the impression they are going down , more and more every month (
