Marvel vs Capcom teaser trailer

The intertubes are abuzz with the new Marvel vs. Capcom teaser trailer, featuring Ryu vs. Wolverine, Morrigan vs. Iron Man (Can Tony Stark possibly resist a succubus??) and Hulk vs. Chris Redfield.

Speculation is rife as to what other characters will be playable, old standbys like Spiderman are almost assured to make an appearance but there are so many possibilities and so far all we have to go on are some silhouettes in the Marvel Logo. Deadpool possibly? Who knows?
