Hey. Sorry, but I think we might be waiting a bit for new enemy territory maps(official/custom) to come out according to what I have read around the web and
this chat log at gamespy . I am not even sure if all of the official tools and such have been released for custom map development yet.
I think it would be nice if they ported the original RTCW maps into ET! Of course that would never happen though because then no one would buy RTCW.
BTW - ever tried the Wild West mod for RTCW? Yeehaw!
