Yes yes, Steam please!
This game was pretty much a must buy for me anyway (BG's spiritual successor? NWN style toolset for infinite content? SIGN ME UP!)
The lack of SecureRom is a total boon and assures a lot of folks who pirate simply as a form of strike will instead buy the game (if they want to play it of course.) I'm sure it won't stop piracy of the game, but it will assure a lot more people buy it than otherwise.
Now if we could only hear word if this will hit Steam at release or not. I buy 95% of my games through Steam and have actually passed up on games simply because they weren't on Steam. So in this case, a Steam release would simply be icing on the cake.
