Free Radical released a pre-E3 footage of Haze, during the video there was no mention of a Xbox 360 version and the last seconds of the video show messages of a possible PS3 exclusivity and a big announcement in this E3.
At Haze website there is no Xbox logo, only PS3.
We will know whether this is true or not next week at E3.
Update
Images added, if you don't want to see the entire video
