a) nobody knows when Clash got changed. For about half a year, the only version of clash anyone knew was NYCC, and even that build was already out of date when we saw it. Clash could've gotten changed internally before the game even got shown at EVO. We'd have no way of knowing.
b) For the last time, nobody balances a demo. Ever. At whatever point is was decided that a portion of the game should be shaved off and boxed up for a demo, that is where the characters, backgrounds, everything, were locked. Nobody ever went back to make sure they fixed this Batman glitch or that WW combo. They said "holy shit it compiles, holy shit it compiles" made sure it didn't crash after 10 minutes of play, and shipped it off to Microsony for certification.
The end.
