Starcraft II, WoW and CoD expansions, then Diablo... so ATVI will do well, but as has been pointed out, subscriptions are not what they used to be. On the brighter side, Activision is unifying Battle.net and it will somewhat resemble Steam. I can see a fee for battle.net use (for all games) in the future.

In sum: its not going to see 18 any time soon but has potential. :top:
