We submitted our first QA build to Interplay in mid-June. That's pretty much our alpha milestone, though some of us think it was alpha a little earlier than that.
Nothing is set in stone just yet.
You could use this to boost the moral of a line of creatures that you're just about to send into a fist fight. Well, I play a lot of UT and Q3 online. I was talking to a couple of Interplay suits yesterday who suggested that I should keep my mouth shut on this. All I'm allowed to say now is Fall 2000. I can tell you that we are moving VERY rapidly and the team is aiming for September 1st to finish off the known issues.
