I've seen 50-70 ppl on ATAG during the weekend. And I'm starting to have some good fun therein.
The main issue online, apart from the wrong FMs and the remaining bugs, is that the Channel map is really huge, and the contacts are more difficult to spot than in Il2 Sturmovik. Online missions with the time will be more varied, as it wasp in Sturmovik, squads will start to join and eventually the online wars will start again. But already, for example, the AI bomber formations are nice to watch, and there are some good fighter engagements from time to time.
2012 will be CloD year
