Predictions:
Things I'm Sure of:
-More information about customized movesets.
-More information about 3DS <-> Wii U Connectivity
-At least one newcomer
-Repeating information from the Direct
Things that might happen:
- The rest of the original cast (Ness, Cpt. Falcon, and Jigglypuff) might be revealed. Or at least one of them.
- Ridley confirmed to be a boss character and not playable.
- More concrete 3DS date. It's pretty much summer by the time E3 rolls around, so...
- Information about the Tomodachi Life stage on the 3DS?
- More information on the online modes.
Things that might not happen:
- Pac Man and Mii reveal. I don't see it. If it happens, great, I'm wrong. We get another creepy character (SFxTekken nightmares) and a character who potentially has a penis for a face. Win/win. To be fair, with Tomodachi Collection/Life... Mii isn't too farfetched. I guess.
- Wii U Specific mode(s) revealed. It's coming out in winter, I'm banking on the fact that it's because they have a lot more to work on in the Wii U version and they're going to try to make it worth the wait before revealing it.
- Specifications on which stages will not get Final Destination versions.
Things that I want to happen, but more than likely won't:
- More Majora's Mask representation
- Master Hand reveal
- 3DS XL Smash Brothers bundle
Things I just don't want to see:
- People whining or coming up with scapegoat reasons of why Ridley isn't playable.
