The character speculation should probably be taken elsewhere, since there have been multiple warnings against posting speculation regarding the character select screen, rather than the leak itself and other E3-related topics.
On another note, I just thought of something. Despite the fact that I am one of the biggest supporters of this leak, a potential issue with the leak just occurred to me.
The 3rd and 4th pics were posted (I believe) before the 6th pic, and supposedly came from the same IP address as the original 2 pics. When the 6th pic was posted, the OP stated that the tourney version contained Little Mac, Mega-Man, and an unlockable Ridley upon completing the tourney. This happens to be EXACTLY what was shown off in the 3rd and 4th pics, which seemed to have been posted before the 6th pic.
Point being, the original leaker confirmed details that came from the 3rd and 4th pictures, which have several minor inconsistencies with them and are generally seen as fake. However, I should also add that the 3rd and 4th pictures were posted on a different web site, which doesn't make any sense unless they were from a different person.
In summation, I am ****ing confused.
