Look promising so hopefully it'll deliver. But the release date isn't the greatest given that Gears 3 at the very least is released then, and possibly Killzone 3. Capcom nailed SFIV's release date last year since it was the only good thing in Feb.
More to the point, it'll be competing directly with Marvel vs. Capcom 3, which is perhaps the worst thing it could possibly do.
And whoever mentioned Li Mei and Khameleon, I think you must be sorely mistaken. I can't see them anywhere. I can see a really generic looking woman behind Kira, but that's it.
Good spot on Daegon and Reiko though. With seemingly random characters popping up in the backgrounds, it seems to me that there might be a lengthy konquest mode, with the character models used in that being re-used in stages, like in MKD.
And using characters like Daegon makes me think it won't be a reboot. But even if it is, that could be the 'unforeseen event' at the end of MKA, a time-slip back to the first tournament, or going by the MKII arenas, the initial stages of the war, in an attempt to change the course of history. but who can say?
EDIT: If this is a reboot completely seperate to the other MK games, we're going to have to start numbering the universes like in Marvel and DC. There's the mainstream series universe, the new series universe(sort of like 'Ultimate' from Marvel), the MK vs. DC Universe... er... universe, the Shaolin Monks Universe, plus the films, comics, Conquest and Defenders all have seperate continuities. Things are getting compli... sorry, komplikated.
