Haze
Confirmed Platform: PlayStation 3
Rumored Platform: Xbox 360, PC
You don't need Nectar-enhanced perception to see that Free Radical Design's latest shooter, Haze, is set for sole release on PlayStation 3. During Sony's E3 presser, Ubisoft officially confirmed it as a PS3 exclusive. Even Ubisoft's fact sheet states, "Play both sides of the same war and experience two unique game systems, exclusively for the PlayStation 3." There was certainly no question about the game's exclusivity given the company's clear statements--until investors were told in late November of its delay.
The sheet, which is dated November 1st and hasn't been updated since, was written well before the decision to delay the game until spring. Could the delay be for the purpose of porting Haze to Xbox 360 and PC? The smaller base of PS3 users could be prompting Ubisoft to port the game in order to recoup costs, especially given Haze's limited press coverage. It isn't a foreign concept to the company -- take former PS3 exclusive Assassin's Creed, for example. Much like that game, Ubisoft spokespeople are remaining quiet on the subject, refusing to respond to our requests for comment.
Chance of Xbox 360 Port: Slim to none
This is a PS3 party all the way, and Haze doesn't currently have enough buzz to warrant a multi-platform port. If it's a sleeper hit upon release, though, an Xbox 360 version is possible.
