Hideo Kojima said in order to release the collection on the system, it would take too much work due to the amount of data in the game.
“I’m sorry to say an Xbox 360 version isn’t being released, because an Xbox 360 version of MGS4 hasn’t gone on sale,” Kojima said. “To explain the situation, the amount of data in MGS4 is just too enormous.”
Since 360 doesn’t use Blu-ray, MGS4 would take up seven DVDs.
“I want to put it out [on Xbox 360],” Kojima continued. “But we won’t be releasing it. “When the next Xbox console [comes out], maybe we can release it [The Legacy Collection].
“If we released a version on the Xbox 360 without MGS4, then it’s not The Legacy Collection.”
