Yes, it has been out for awhile, either as a digital distribution on PC (only the German PC release got a physical edition of FoV) or as part of DKS on either Xbox or PC. The North American release of DKS is set for April 12th (with pre-order bonuses); there was no PC DVD release of DKS in either the US or UK. If you install FoV on the PC, there is a patch to convert the game to DKS, though that will break save compatibility with D2:ED saves.
