When it comes to trailers, RE5 is going the same route as the MGS series. They're releasing little tidbits here and there which may be spoilers or they're just pulling our leg. For example, at the end of one trailer it was announced that...Jill Valentine is dead!!! But that could be BS and just used to get people talking. I doubt they'd reveal something like that in a trailer. Then again, when the trailer came out for RE4 they revealed Ada Wong was in it which I thought was a huge spoiler.
