I imagine that Nintendoland's relative failure (now followed by Game & Wario's failure) has resulted in falling confidence in their casual ideas, while their safest title so far (NSMB U) is the only performer, so doubling down on that things like that probably looks like the best idea from their perspective.
Yeah, so the question is, what is the new "Nintendoland" going to be? The Wii get a foothold thanks 100% to Wii Sports. As Nintendoland failed to sell the Wii U's gimmick, they really need to find something that isn't safe and takes full advantage of the tablet.
I just don't know. Looking at the fall's Wii U slate, I'm not sure what game they could pack in to get this thing to sell. They really need a Minecraft type of game changer to get people to drop another $300 on a console that plays HD versions of the Wii games they already own, as the system isn't powerful enough to run the near-CG looking stuff shown on Xbone and PS4.
Oh I feel quite confident it will do better than that. Nintendo games have a lot better legs than other titles.
The "legs" concept is irrelevant to a console without a system seller.
