I think the major reason for people bitching about the E3 presentation or to be precise, the WiiU presentation, was that Nintendo themselves showed a lot of future titles when the 3DS was first announced in 2010. We had Kid Icarus, Paper Mario, Kingdom Hearts and Luigi's Mansion – and none of these titles was a launch window game. KI came out in March 2012, almost a year after the 3DS' release, Kingdom Hearts is due in July and Paper Mario as well as Luigi's Mansion are due this holiday season.
Compared to that, Nintendo has shown nothing that goes beyond the "launch window" period. We know there's a new IP coming from Retro Studios and we know of the "usual suspects" – meaning Zelda, Pokémon, Smash Bros and Mario – but there is nothing beyond that.
