Of course I would guess Black and White 2 / Black and White contributed heavily to DS software sales, with B&W2 released fall 2012 - plenty of people would be buying that for their 3DS due to backwards compatibility, and I'd consider it basically a cross-gen game (it'd probably have had a 3DS and DS version if it wouldn't have caused issues for trading).
Still not great for the Wii U of course, but just thought it's worth mentioning that it's not like ancient games on a dead console were selling more than it.
