SLP2000: they said on their forum that
"I think it's safe to say that LoG will not be Steam exclusive."
They did? That sounds awesome, especially since I think they are aware that part of the people who are passionate about it are hoping for a DRM-free release. Here's hoping they will offer it, either on their website, the
Humble Store, Indievania or client-free Desura - I could even live with "DRM-free" GamersGate; I don't dare hope for a GOG release though, that would be too good to be true and doesn't seem very likely.
