I wonder how it's gonna do through Q1. Pikmin being delayed again is a bit of a blow, and as far as I can tell, Japan only has three games coming (Fist of North Star 2, Black Ops 2 & Need for Speed Most Wanted. Not too sure if BO2 is already out there or not).
It's going to be a good time to judge the base level sales of Wii-U, at least.
In the west, I think Lego City might give it a sizeable boost, Lego games have found quite a home on Nintendo consoles in the past. Rayman should helpt a lot as well. I'm not sure what Wii Fit U & Monster Hunter will do, but at the very least they're going to do nothing to hurt sales :P
Regardless, congratulations2u Wii-U. Out of the gate well. Onwards and upwards.
