Diablo 3: Ultimate Evil Edition is being developed for Xbox One alongside the previously announced PlayStation 4 version, Blizzard has told VideoGamer.com, but it can't yet confirm whether the game will ever see a release on Microsoft's platform.

"I don't know where we are with Microsoft right now so I can't really comment on what that contract looks like," Diablo 3 lead producer Alex Mayberry explained to us this morning while discussing tomorrow's launch of Reaper of Souls. "The point is we are developing for Xbox [One] and PS4 simultaneously. We hit those major platforms and then our goal as a development team is to make them run."

Mayberry says that "it makes more sense" to develop for both next-gen consoles simultaneously, even though a release on Microsoft's console has yet to be confirmed.

"We have that pipeline worked out," he continued. "We've already done it with the 360 and PS3, so that team knows how to develop at the same time for both of those platforms. That's just what we do. And then Blizzard and Microsoft can work out whatever they work out."

As for when Ultimate Evil Edition is due to release, Mayberry says that "it's not far off... [The console team] work in parallel development with us so they're not far behind".

Blizzard's non-committal stance on an Xbox One version echoes that of the last-gen release of Diablo 3, which was originally announced for PS3 but later confirmed to launch simultaneously on Xbox 360 and PS3.

Diablo 3: Ultimate Evil Edition is set to include both the original Diablo 3 and expansion pack Reaper of Souls, the latter of which launches on PC and Mac tomorrow, March 25.
