From what I understand, the bar hasn't been set very high. The unanimous "best E3" for Nintendo is 2004, right? I think it can be beat.
The NX is not enough though. Neither is Zelda. If it's just a hardware win, it won't be. If they can drop some software bombs that aren't just Zelda, I think they could do it.
But what could beat the 2004 TP reveal that isn't Zelda? They could reveal Mario NX. They could announce a 3D Donkey Kong Planet, since it's pretty much confirmed that Retro hasn't been working on Prime all this time. (something I called)
They could tease Metroid Prime 4. They could actually announce Nintendo vs Capcom and Diddy Kong Racing Returns as the NX's parallels to the Wii U's Smash 4 and Mario Kart 8, since it will honestly be way to soon for NX iterations of those games. They could announce F-Zero, but you don't win E3 with F-Zero, no matter how good it is.
Or hey, they could even announce a real mainstream western exclusive. Probably not, though.
