He made similar promises last year.
That said, I'm inclined to believe him this time, because literally person from Nintendo that presented last year, from Miyamoto to Dunaway, admitted that they royally screwed the pooch. To stem a bit of the hate, Miyamoto even announced a game that he had no intention of announcing (Pikmin 3), and Dunaway... while, she told us to keep playing SSBB and Mario Kart XD.
Hopefully she's Dunaway with sooner rather than later.
(*shoots self in head for the last line XD)
