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.
