Shocker. Mario sells. It's no Angry Birds but its up there
Point being, it needs a barage of quality titles. For every Mario, it'll need Drake and 10 of his best buds available. I get it. Give this system some time to get its ducks in a row.
Thing is, the way things are going Drake's best buds will be defcting to 3DS. It's going to have both the blockbusters and the solid support, which is usually how it works.
You'll have to dig in the June 2012 NPD thread for the source.
