Another leak showing of the game's roster exactly the same as before. But this time, there's also a screen informing the player he has unlocked the All-Star Mode, where you can face off against every character, implying heavily that this constitutes all the characters. Wolf is definitely not here. Mii Fighters are noticeably missing, but no-one knows how they're going to work as far as the roster goes.
I'm pretty sure this is the final version, not the demo version that was playable in Japan earlier this week. However, roster space and the fact that this is the 3DS version (as opposed to the Wii U version), makes me hopeful for DLC characters, especially if Nintendo wants to add some additional incentives to pick up the game on Wii U that they essentially already have on the 3DS.
