It's one of the worst lineups they ever had. Maybe not as bad as Wii Music christmas, but still pretty bad. Maybe you're satisfied with Nintendo putting less than the minimum effort into their first HD console (even shitting on the mainline Mario legacy without shame), because the higher ups were too incompentent ever since the Wii died, but that's not gonna reflect in the mainstream.
Literally the whole holiday lineup looks like either 3DS- and/or last gen games - unless you do side by side comparisons, which just proves the point. Families will go for the much cheaper and superior 3DS, maybe even the original Wii, rather than getting the overpriced WiiU which doesn't have a single unique experience (Sonic could have been an argument, but wait, also getting a 3DS version) but still charges 100$ more for that redundant ass gamepad.
It's on a smaller scale, but you could already see it with Monster Hunter and Lego City which only sold somewhat acceptable on the 3DS, even though the versions were inferior. Because the 3DS is a good system, while the WiiU can not offer anything that's not available through more attractive options.
