Now it appears that this year, Unreal fans will be feeling a sense of déjà vu vis-à-vis the latest installment in the series. Today, representatives for Midway Games, which took over Unreal publishing duties from Atari in July 2004, announced that Unreal Tournament 2007 will not be released in time for the 2006 holiday season.
"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.
