From the following 2 pics and everything we've seen and heard so far, it looks like the final roster of playable characters (including pre-order exclusives) is going to be 22 in all, 11 for each side. Even though they weren't able to "officially" reveal all of the characters (you'll notice some of the names are blurred out) my guess is as follows....

Dude relax, The game hasnt even come out and your demanding info on the dlc pack. Worry about the actual game first. But to somewhat answer your question. It is likely that the pre-order characters will be in that dlc pack
I only accept those pictures as a list of absolutely confirmed characters, not a final roster. What say we stop fussing over the final head count until it is explicitly confirmed as a final head count, hmm?
