@Gia:
Dude that site is starting to sound extremely fake. First FFVersus13 to FF15, now SSB at E3? Sakurai just started working on it. You really think he has a build ready and playable by next week?
No. but it would be cool. (btw it is just a rumor. most of the stuff they post are some unconfirmed statement from a site that got the statement from a "mysterious source" just like this one.)
