Ryan has also stated this morning that there are no intentions of doing a 64-bit version of Unreal Tournament 3 for Linux. Though if time permits, he may produce a x86_64 build anyways. On a positive note though, the editor for Unreal Tournament 3 (UnrealEd) now uses wxWidgets on all platforms, which helps in making it cross-platform for Linux. UnrealEd for UT3 will be made available for Linux at some point in the future.
