AVault is reporting several things related to the Unreal Tournament demo this evening...first off, the demo will be "released before Saturday" and will in fact be for 3dfx cards only. "A few days later" Epic will release a demo that supports both Direct3D and OpenGL. They're also reporting that contrary to rumor, UT has not (yet) gone gold.

Update: a member of the UT development team has informed us that, "the demo will most likely hit the net on Thursday with the full version following around Sunday or Monday (the full version being the one that supports Direct3D and OpenGL)."
