If you want to play Bayonetta 2 and The Wonderful 101, you’ll need a Wii U. Hideki Kamiya wrote on Twitter today that Nintendo is (unsurprisingly) funding the projects. When the two games are ready, Nintendo will publish both releases worldwide. The company would have to approach Platinum in order to get the ball rolling on Bayonetta 2 and/or Wonderful 101 ports.
“We’re a development company…Nintendo gives us money, we make Bayonetta 2 and W101, and they sell it…So if Nintendo says ‘We’re putting Bayonetta 2 on PS360′ it’ll come out on those platforms…So ask Nintendo about it…”
Kamiya tends to troll his followers, but I’m pretty sure he’s being serious here. And considering Nintendo would be very unlikely to approve or even suggest PS3/360 ports for the two Platinum Games, they’ll remain exclusive to Wii U.
