Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
I think its a case of wait and see how BF2 turns out, for all we know it could turn out crap.
It does mean that its atleast two months away, you know how game release dates get constantly pushed back.
There are some large beach areas on the single player HL2 game, so either the mapping team took a long time or there must be an effecient way of creating terrain.
