My baseless, speculated predictions for "surprises":
- A big western 3rd party multiplat previously not expected to come to Wii U will end up being announced in the US stream but not the Japanese stream
- Atlus will announce an exclusive that is in the Japanese stream but not the US stream
- Ubisoft will announce ZombiU2
- Sega's 3rd game will be casual-bait and unappealing to gaf at large
- Nintendo's next big collaboration will be with Capcom but it wont be Nintendo vs. Capcom or Megaman related, may be a new IP
- Tecmo-Koei will announce a surprise exclusive
- There will be a sizzle reel for eshop indie games
- Monster Games shows a Wii U title that's a racing game but still somehow not F-zero or Wave Race
