As of now, there is a huge project over at OldUnreal.com to develop the Unreal 227 patch. I am sure that countless hours have been spent on taking in information, programming, and other developing related hurdles. The release date has not been set specifically, however I will definatley anounce the coming of the 227 patch on the website. I understand that there are a number of mapping projects being developed in the unreal community but no big releases yet (if you are making a release soon please let me know!).
