I think everything's on the table already. What more could they possibly reveal.
Here's what's coming from Nintendo: 3D Mario, Zelda, Smash Bros, Mario Kart, Wii Fit, Pikmin, Xeno RPG, NSMB U DLC. That accounts for every internal team of any quality.
I don't see how they could be holding back any big guns for E3, just that people want them to do so. That big ND was every announcement they have. What will be at E3 will be more specifics and playable versions.
If people are thinking there are big unannounced third party titles.... lol.
