It was attached and debuted with The Avengers. Likewise the final trailer for The Dark Knight was attached with Iron Man and Inception debuted with Iron Man 2.
a trailer will debut in 4 weeks then the choices would seem to be it'd be attached with either GI Joe 2 (March 29th), 42 (April 12th) or Oblivion (April 19th) but I'd be more inclined to believe it's either G.I Joe or Oblivion given the two are also major IMAX releases and Warner Bros. partnership with IMAX.
