Also, we're talking about a Teaser Trailer, and Teaser Trailers often don't have any actual footage frm the Film, so, if that's the case, if it's just going to be a Logo, and a Voice over, and maybe some reused footage from the First movie, I wouldn't expect that to be in 3D.
First full trailer (Possibly with The Hobbit?) yea, maybe it'll be a 3D trailer.

Where are we going? And why are we in this Handbasket?
