Presumably they won't delete the actual SGA, just remove it from the module.
Exactly
can eirr at least host them on their page so people can download them for single game uses even if they are taken out of rotation or will this cost too much bandwith ?
If I am not mistaken, the map will still show up in your THQ\companyofheros\archives folder. It just wont show up in game.
If you and a group of people wanted to play that map: make a copy of the SGA and rename it betamap1.sga
Everyone in that game would have to do that process.
