World of Warcraft could yet be released on iOS, providing developer Blizzard can find a way of acceptably mapping the MMO’s controls onto touch screens
“You've got to put an interface, what do you do?” WoW senior producer John Lagrave told Eurogamer. “Maybe we'll stumble on the great way to put WOW on the phone - maybe we won't, but we're certainly looking into it.
"We won't do it until we think it's decent. So we certainly look at that, but we just haven't solved it. What we've done with WOW [with the World of Warcraft Mobile Armory app] on mobile devices is very simplistic: view the armoury, you check your auctions – not just on mobile but also on web.
"When we have an epiphany, everyone will know. But for now, no epiphany!"
Lagrave also stated that it’s possible the studio may choose to port a portion of the game – such as a fishing mini-game or pet battles – to iOS, although nothing has been confirmed as of yet.
