E3 should be awesome. With PS4 and Nextbox launching, I expect at least one megaton each in the form of a game, an exlusive 3rd party deal of some kind or a former exclusive going multi-plat. With Nintendo now having 2-3 years for most teams to work on Wii U games, I expect no end to what we'll see from them. I think their fear of losing market share will also lead to some 3rd party announcements.
While many have speculated on some PS or XBox megatons like Gears of War, Gran Turismo and others, I think the company most under pressure to deliver is Nintendo and I think they will. Possible Megatons:
-Nintendo shows a breathtaking game. This could be visually, gameplay or both. I have high hopes for the 3D Mario game and the Retro game. I think they will both push graphics on a level with the best we have seen yet, while incorporating radical new themes and possible gamepad-centric multiplayer. Another possibility is a Wii-series game that mixes up the status quo.
-Significant 3rd party Wii U support. Either in multiplat or in exclusive, I think significant 3rd party franchises will be revealed. Final Fantasy, Metal Gear or something from Capcom are the most likely candidates, though I still think GTA5 is Wii U bound.
-Wii U price drop/bundle/new services/3DS link. Something to kick Wii U up a notch at the same time major software launches and in time to battle next gen competition.
-3DS re-design that links with Wii U in a greater way.
-NFC product. The next big craze, this collection product will be something huge.
