Hopefully the Steam versions won't require some third party DRM on top of Steam's own DRM, like some games do. Hell, it would be great if retail copies of the game didn't have any DRM beyond a disk check (including a Steam requirement). I just wonder how likely that is in this day and age. If they just stick to a disk check, that would be great, but if they do decide they want some form of increased protection, to at least slow piracy,* then personally I'd like to see them use Steam's. Although that is because it's not really a hindrance if I'm already happily using it, that's obviously not going to be true for everyone. *A disk check is pretty much useless at stopping zero-day piracy, copies get "acquired" a few weeks before official release and cracked without much difficulty. There'll always be people who are anticipating a game and if they see they can play illegitimate copies before release, they will. To what degree that effects release day sales is a different matter (I'm sure there'll always be people who will buy the game when it's released and also people who would have bought the game but then failed to see the need after jumping the queue with a pirate copy).
