According to Stephen Totilo's blog, multiplayerblog , the Gamestop/Ubi Haze promotion has been cancelled. In fact, it was never meant to be. Ubi PR told Stephen the announcement was the result of a miscommunication and it was rectified.
Ubi has among the best, if not the best internal development in the world. They are supplementing it with external developers like Free Radical on games like Haze. They respect their product enough to jump in and rectify a situation like the Gamestop promotion. There are publishers out there who would not have made the correction. Sounds like the product deserves our respect too.
Good job Ubi!
