Diablo III was shown off this weekend at PAX East and up to now it had appeared that it was a Sony exclusive, given that it's only been announced for PlayStation 3 and PlayStation 4.
However, this may not actually be the case as in an interview with Penny Arcade Report, the game's lead designer Joshua Mosqueira clarified Diablo III might actually make it onto other systems as well.
"We don't have any announcements to make at this time. But we're not necessarily a Sony exclusive."
Blizzard Entertainment's Chris Metzen announced back in February that the developer had entered into a "strategic partnership" with Sony to bring Diablo III to its home consoles, but it now seems likely that it will eventually be made available on other systems. Could it be feasible for it to make an appearance on Wii U? Only time will tell.
