I just got back from Epic moments ago and thought I'd share this little morsel with you. It looks like the Unreal Tournament 3 demo will be released this Friday. They were putting the finishing touches on it last night; didn't want to release it the same day as the Call of Duty 4 demo (Thursday), so Friday appears to be the big day for the UT3 demo. Stay tuned for the full hands-on preview after I type it up (cough).
ETA for the PS3 demo? Never!
