Great news! This and 360 implementing IE9 (Aye.. It's IE9.. But what else where they going to use?) could mean very interesting times for C2 game dev.

Well, they could make a proper browser, then release it on 360. <img src="smileys/smiley36.gif" border="0" align="middle" /> Just a suggestion.
This is great news though, I didn't really consider the possibility of C2 games on Steam when I read about Greenlight earlier.
