Diablo III with its Reaper of Souls expansion, don't hold your breath. A recent dev interview really put the kibosh on that idea: Lead designer Kevin Martens stated pretty clearly that dividing the community into online and offline groups is not now, nor will it be, in the cards. When asked about the offline mode in Diablo II, he pointed out that the community back then was very unhappy about that division and added:
"That was the wrong choice to allow people to play offline, and we still stand by that. And we think Internet access is widespread. If someone has no Internet access, then yeah, Diablo III is not the game for them."In the interview, Martens and Art Director Christian Lichtner also talked about the direction of Diablo's III and the game's economy sans auction house -- notably, that stockpiling items before the change won't give much of an advantage because the post 2.0 patch economy will be full of new items that can be acquired only through play.
