Quote fromIt's Blizzard, they've been making a deal about this patch for years. Before Bashiok collected ideas, NickJS was collecting ideas, back when Tech Support was in charge of moderating the forums. I guarantee they'll have something other than bug fixes to show for.
I don't think the Diablo II suggestions/concerns were for Diablo II developers. You'll note that EVERY one of those suggestions made it into Diablo III.
