I dunno, I've got mixed feelings about this... looks like another step in the ACTIONhorror genre, but then again most reveal trailers these days go for lots of explosions and action to get people pumped.
On the bright side we are seeing some cool looking creatures, straight up zombies, and grab attacks. Though on the down side it sounds like the game will be something of a sausage-fest... (Here's to revealing fully playable female characters right?)
I think my favorite part of the trailer is when that generic marine/soldier dives for cover like he just got out of Gears of War, and immediately get's yanked from it... though I hope it's just a "take that!" to cover-based shooters not a sign that RE will become one.
I will be keeping an eye on this though.
