Any time soon a patch for PC will be released. We'll slap a download link in this post once the patch is out.
If you are interested in the "pre-patch" talk, here's the CM forum link

haven't seen a post here in a while. Well, there is a patch 1.01 out which caused the community to get angry ("game now shows version number" etc) because it basically addressed only minor issues and some minor MP stuff. Nothing special or even worth patching, it seemed.
Then there is a free DLC out, combined with a patch, that adds 4 MP maps and 2 campaigns which can be played both SP and MP, and something like a tour around the isle to explore those 220km² of terrain.
Now a new Patch is in the making, no release date known as of today, but quite a bit of a patch log which seems (again) to mainly address MP gaming. No dedicated servers possible though (many people wanted that).
Apparently there is another DLC in the making, too.
