I doubt there are that many people like you who would really not play because of DRM (i.e., many people don't even know what the big deal is). In my mind, many of these people who profess to be anti-DRM would have downloaded a hacked or cracked version of game. I could be cynical, but I can understand why the companies want to protect their games even if the method is BS.
In any case, it seems like more people would skip these two games in favor the free-to-play League of Legends, which appears to be eclipsing both in terms of no. of players. Different game type of course ... but not to burst any bubbles, SC2 SCBW and Diablo 3 D2
