Resident Evil 6 Trailer WTF Moments

The new guy's blood seems to be the key to stopping the infection and he's willing to help the world... at the right price.

Chris has a serious vendetta against a female character and exclaims, “How many of our men are dead because of that bitch?” I'm wondering if he's talking about Ada Wong, or is it a gone-bad-again Jill Valentine that's causing Chris's BSAA problems?

In the history of the series, outbreaks have tended to be in one location at a time. But Resident Evil 6 seems to put the infection at a global scale, occurring not only on domestic soil, but also in an Asian city and possibly other foreign lands. How will the gang take down multiple threats occurring at multiple times, and are the bio-terrorists that organized?

Resident Evil 5 was maligned because of its co-op action, and this trailer provided no clear answer on whether co-op will return in Resident Evil 6. In some of the sequences we see two characters interacting and working together (Mystery Man and Ashley), but in others we get the lone gunmen of Leon and Chris putting down the hurt. Will we get co-op or is the series returning to the classic solo experience?
