Haze-related news, rumor and speculation have been doing the Internet-rounds over the weekend regarding the fact that the game is a PS3-exclusive. You may recall Spong's coverage of Sony exclusives as mentioned at E3 in which Haze was pegged as PS3-only at least until the end of the year.
This - plus comments made a Leipzig, plus the fact that all mention of any other platforms has been removed from Free Radical's Haze web-pages - has apparently lead to the conclusion that the game will be PS3 exclusive.
So, Spong spoke to a representative at Ubisoft who spoke slowly and clearly to Spong, explaining, "Basically at E3 it was announced that the game would be PS3 exclusive for Christmas. That's where we stand - other platforms have not been ruled out but nothing has been confirmed."
Therefore, right now Haze is exclusive until Christmas... and then might or might not be.
