The trailer has been released for the upcoming straight-to-video DVD release of "Death of Superman" or "Superman/Doomsday" or whatever they're calling it.
The copy written for the VO on the trailer sounds like it came from the desk of a WB Home Video intern, or else the studio totally missed the attempt at retro trailer copy with lines like "See! The Amazing Superman! See! Him Perform Amazing Feats!" Anyway, I think if you just look at the footage itself, it looks pretty cool.
It looks like the story has been greatly altered from the comics, cutting out all of the extra storylines and, it seems, dumping the "Rise of the Superman" storyline, which leaves the "Return of Superman" storyline in some serious doubt. But he does come back with the Super Mullet, and that's got to be good.
