they have been working on this game for years,therefore they didn't really cared about consoles but surely kept in mind while developing that there already was a successful diablo game on console,therefore the release on ps3/4(and i'm pretty sure later on xbox3)is no surprise as a port isn't expensive but generates tons of money.
what I don't understand:why are they complaining?Without consoles most AAA pc titles wouldn't exist and one lousy pc exclusive ported to consoles?who cares?
