My initial though is, "Eh... it could work." It doesn't look bad - cool action flicks are always welcome to me - but it really depends on what shows it's up against in April.
Also, keep in mind the trailer music is almost NEVER the music of the final film - I think that was the "let the bodies hit the floor" song popularized by Jet Li's The One, but I could be wrong.
I wouldn't expect the next "Terminator," but I don't think it will be terrible, either.
