They are planning to release all the new maps all at the same time, so it will proably take them awhile still to get Goldrush into the batch of maps. They are coming though, it just could be awhile. As for new medic stuff, it's still up in the air as far as if xbox is getting it or not. Personally, I don't think Valve is going to release that stuff ever, but I have heard we will get all future PC maps for sure.
