Could These Be the Last Two Marvel vs. Capcom 3 Characters?

As Marvel vs. Capcom 3 nears its release date on February 15, the final two characters have yet to be announced.

However, someone who has been leaking very accurate MvC3 information thus far has said that the last two are Hsien-Ko, from Capcom's Darkstalkers, and Sentinel, from Marvel's X-Men.

I believed that, and then I found this:

So now, I don't know what to believe.  Judge for yourselves.

UPDATE: These are, in fact, the final two playable characters in the game.
