Epic's Mark Rein made a massive update to the official Unreal Tournament web site, with a general status report on all things UT (thanks Frans). Amongst the topics covered is word that listen servers will appear in the server browser as of the next version, lots of Direct3D issues, and this general update:

The new demo has been a fantastic success from a testing standpoint. We've been able to isolate all kinds of problems and find some good solutions. Yes, yes, yes we should have done this for Unreal way back when. Lesson learned. Don't forget that we do fully intend to release an updated D3D patch for Unreal itself once we get the D3D performance to a level we're totally happy with. Unreal Engine licensees all get access to Unreal Tournament Engine source code so future games based on our engine should hopefully incorporate many of the improvements we're making now, and in the coming weeks, thanks to the release of this demo.
