Platinum just shot themselves in the foot.
I don't know how much the rest of you know about Japanese culture (I'm an expert), but honor and shame are huge parts of it. It's not like it is in America where you can become successful by being an asshole. If you screw someone over in Japan, you bring shame to yourself, and the only way to get rid of that shame is repentance.
What this means is the japanese public, after hearing about this, is not going to want to purchase Bayonetta 2 for the Wii U, nor will they purchase any of Platinum's games. This is HUGE. You can laugh all you want, but Platinum has alienated an entire market with this move.
Platinum, publicly apologize and make Bayonetta 2 multiplatform or you can kiss your business goodbye.
