Blizzard just shot themselves in the foot.
I don't know how much the rest of you know about American culture (I'm an expert), but honor and shame are huge parts of it. It's not like it is in Canada where you can become successful by being an asshole. If you screw someone over in America, you bring shame to yourself, and the only way to get rid of that shame is repentance.
What this means is the american public, after hearing about this, is not going to want to purchase Diablo III for either system, nor will they purchase any of Blizzards games. This is HUGE. You can laugh all you want, but Blizzard has alienated an entire market with this move.
Blizzard, publicly apologize and cancel Diablo III for PS4 or you can kiss your business goodbye.
