They are just going by just seeing one version. They do not have any word from Valve that a PS3 version isnt planned or in the works. If memory serves me we only saw the 360 version of GTA4 for a while then they showed the PS3 version. The opposite could be said about UT3.
Until Valve states otherwise, its not 360 exclusive.
