I just checked their ftp site, as tyedyeboy said, and I think he's right. They do have files inside some "volumes" directories which look like they could be the episodes. Haven't downloaded them though since they're pretty large.
Its not really of interest to me since I already have a few copies of WCP Gold, but if you CAN dload the episodes from the secretops ftp site, then surely that would be legal wouldn't it?
Just out of curiosity too, has anyone had any success getting EA to upgrade your WCP to the Gold version? Before I got Gold I tried to do this, but got no reply at all. Anyone else had more luck ??
