The first brand new game to be sold through GoG will be CD Projekt's very own The Witcher 2.

Hopefully it won't be overpriced like other new games sold through digital distribution. Seriously, CODBLOPS was 60 Euros on Steam, whereas the cheapest I could find it in brick and mortar shops was 30 Euros. Outrageous. 
 
So, will you be getting the downloadable version or the disk version?
