Capcom putting copyright notices on Oni, Evil Ryu videos

Also, it appears that Yoshinori Ono, the title's producer, has taken some heat for the early reveals, which he posted about on his Twitter account.
It hasn't been confirmed how Oni and Evil Ryu were unlocked, but many people have claimed there was a password entered which opened up both fighters. It's unclear when these fighters were supposed to be officially revealed, but considering Capcom's actions, it wasn't at this time.
Both of these characters briefly appeared in an officially released trailer back in early December 2010, although it was simply a teaser image.
