I just don't see how they could possibly drop the ball this year, given what they have to show. Unless they choose to END the Nintendo Direct with Wii U Party or Wii Fit U. Not that those won't be great "casual" games that I'll get and enjoy, but they aren't what the "core" E3 fan is going to get hyped about. Even last year's E3 really wouldn't have been that bad if they'd done things in a different order, like STARTING with NSMBU, then showing Nintendo Land and ENDING with Pikmin 3.
We already know four MAJOR Wii U titles they'll be showing off: Wind Waker HD, 3D Mario, Mario Kart, and Smash Bros., and those first three will be playable on the show floor. Add in some updates on the games they talked about in the January Nintendo Direct like X, Bayonetta 2, Yarn Yoshi, Shin Megami Tensei X Fire Emblem, PLUS more on Sonic Lost World, and some kind of tease or mention of Zelda Wii U (don't expect this til Holiday 2015, but hey, even a concept image would be great). Then finish with a BANG by finally revealing Retro's title, which we all know will be drool-worthy whether it's Metroid, Star Fox, or a new IP. To me, that would be the BEST E3 showing they've ever had.
Also, don't forget they're having a 90 minute roundtable for Pokemon X/Y and we'll hopefully get a blowout of new information from that. Plus, they could have another smaller separate Nintendo Direct on Wednesday or Thursday for 3DS games like Mario and Luigi, Mario Golf, and the Legend of Zelda 3DS, which would only ADD to the greatness.
I think the biggest problem is that everybody thinks that an E3 presentation is ONLY good if there are TONS of surprises. Not that surprises aren't great, but I think people focus too much on just wanting NEW announcements all together, rather than the equally-great surprise of SEEING a game like 3D Mario, Mario Kart, Smash Bros., etc. for the first time. New announcements aren't the only things that are worthwhile. I think seeing the games themselves for the first time, plus getting a better idea of what's coming the 2nd half of 2013 and early 2014 and emphasizing that the Wii U drought will officially be over once Pikmin 3 launches in August is PLENTY. Besides, Retro Studios' game WILL be a surprise, as will the 3rd exclusive Sonic title, and who knows...maybe they will have another game or collaboration to reveal, though I don't expect it. Focus on what we ARE getting and we'll all be happier. They have more games to potentially show off/talk about this year than they've had in the last three or four years combined.
