Nintendo can't support two consoles now that the handheld has development cycles of any significant length (compared to DS games, much less resource-intensive). So they have feast or famine for one or the other. Mario Kart kicked off a good year and a half for Wii U which we're still only midway through. Next year similarly looks pretty good for Wii U but even poorer for 3DS.
Hence why high-portability twin platforms are needed.

Monster Hunter: pissing me off since 2010.
