"Right now, UT 2007 (PC) is slated to hit in the first half of 2007," the spokesperson told GameSpot. When it was announced in May 2005, the game had a broad "2006" release date. Since then, it has moved to a broader "winter" release window, which traditionally extends into the first few months of the following year. The new release window means the game could conceivably not ship until June 2007.
PS3 version may be even later than that.
As for the PlayStation 3 version of Unreal Tournament 2007, its ship date remains undetermined. Interestingly, though, Midway's response did not mention the PlayStation 3 version by name. "The next gen version(s) [of UT2007] have yet to be tagged with an exact ship date yet." Earlier this year, PSM magazine had claimed that UT 2007 would be a launch title for the PS3, which goes on sale in the US on November 17.
