An update to the Weapons Factory Arena page says the Quake3 mod is ready for first release, and they have put up almost all the files right now (weighing in at no less than 60mb), so that modem users can start downloading. The last few files (client and server execute ones) will be released during an IRC launch event tonight, which will be in #wfa on irc.enterthegame.com or pq.gamesnet.net, at 8 PM CST / 9 PM EDT. So, this should be your Quake3 mod of the weekend. Here are some screenshots.
