Well scens/campaigns are not necessary IMHO... But couple good Vietnam maps could be nice to get. I know that WinMBT had some maps but couple (even bigger size than those)more isn't bad thing...
As I said in the other thread, I'm mostly waiting on the patch, to see what changes. Things like the Light Helicopter class getting the FO ability have the possibility of mucking with existing changes and will have to be accounted for.
