I've PM'd the specifics to those who have asked, like yourself, but I would prefer that since it involved a lot of my friends, I'd rather that it spreads once the game is released.
Could I get one as well? I'm actually curious about how everything went down.
Eh, I would not praise the way Capcom handled the UMvC3 leak at all. All they did was slowly reveal characters we already knew were coming (no different than what SuperBot did), and then come up with BS reasons as to why characters people wanted were not in.
If I recall correctly, they said Mega Man wasn't in because he wasn't highly demanded like the other characters (Vergil, Phoenix, Strider, etc.). Which was a complete lie as Mega Man X outranked everyone in a character request poll. Not to mention nobody really asked for Firebrand, Nemesis, or half of the Marvel picks.
The only difference between Capcom and SuperBot is that Capcom had better reveal trailers.
They didn't deny the leak for their characters, or do some throwaway lines like "the leak isn't representative of the final roster" though. They pretty much rolled with it since no one was going to buy them denying it, and the reveals became more about seeing how the characters played than seeing who was going to get revealed. I still remember the Phoenix Wright reveal being looked forward to by many because of it.
