What kind of games, for example? Wii series flopped and Mario didn't move any console, plus was overtracked, which is sad considering the old numbers were already bad.
Proper revivals for Star Fox and F-Zero (because outsourcing them did those IPs no good), a new IP and a real Paper Mario sequel.
In the sum they might only sell about as much as Zelda or maybe a little more, but it's four games to play instead of just one. Besides, everything that is going to be put on the Wii U will be an inevitable flop, because the market is rejecting the console.
