i dunno, i know people who confuse unreal II with unreal tournament II even before this news was out, so well there is a chance. but i think that the project unreal warfare got a new name, witch could be Unreal Tournament II, however original it certainly is not. It wouldn't make sence, cause warfare was to be the successor of unreal tournament, why make 2 online fragging games??
Another clue why it is not a typo is the content of the article, they were talking about vehicle use, and the standard ut weapons got an overhaul, and unreal II is certainly not what they described here.
Time will tell i suppose, looking forward to it no matter whats it called
