For those of you sitting there hitting refresh just waiting, here is word from Tim Sweeney on the D3D / OpenGL Unreal Tournament releasefrom the Unreal Tournament page:

Our plans right now are to release the Linux Server-only version of the Unreal Tournament Demo tonight, do some exhaustive overnight testing (and potentially a bug fix if it's needed) and then give the demo to GT to release tomorrow morning if everything goes OK. There are still a few known issues (Tim Sweeney will post a list tonight on the Unreal Technology Site) that won't get addressed  in time for the demo release but otherwise we think it will be pretty solid and D3D users should be pleased. 

As well of course as the previous quote from Tim Sweney, which Billy got:

We've gone through 4 "release candidates" in the past 2 days and just started testing version version 338 internally now. If everything looks good, it's a go...but it's hard to tell whether it will be tonight or tomorrow.
