If you want to backup the argument that I've seen repeated on these forums over and over: (that we cannot judge Wii U sales because it is too early to tell when you account for future games) then yes, please list confirmed games for the system that will suddenly catapult it into high sales territory.
I bought the Wii immediately when it came out in 2006 because of how unique it was. Several special titles such as Zak & Wiki made the system memorable, but the real reason it sold so well was because A) the global economy was still in a "pre-financial recession) high B) the system invited the family to play and C) the Wii actually held a sizable "cool" factor because of the wiimotes.
Now, the Wii U has launched in the post-financial recession world, families are not clear as to whether the Wii U helps them play Wii Sports in any different way, and after years of terrible support from third parties and the whole core vs casual gamer argument, the Wii U has lost most of it's "cool" credibility.
