There's really never been a question of IF Unreal Tournament 3
was coming to the Xbox 360 but a matter of WHEN the game was going to appear on the Xbox 360. MAXCONSOLE has found
a German magazine that is stating the game will ship out in April for the Xbox 360. That seems about right as it would give the PS3 version a four month window. Honestly I wouldn't expect it until June/July but that's just my opionion.
