Something surprising, and I don't really mean what Retro is working on. I mean something like Pokemon Snap U, or a Platinum Games Starfox title. Another crossover like SMTxFE, and of course more multiplat announcements. And although of course this E3 is all about games Ninty would do well to roll out the TVii service fully and remind everyone they can already do almost anything Xbone can, for free. They're in a better position than any of us could have expected a few months ago to just blow the competition away this E3.
Also, herro everywan! First post, decided to finally sign up and let some of this crazy E3 hype spill out.
