Blizzard is losing players interest in the now seven-year-old MMO, World of Warcraft and to keep things fresh, Blizzard are promising a free digital copy of the upcoming loot-fest, Diablo III to anyone who signs up for the World of Warcraft Annual Pass.

The deal was announced at BlizzCon last week, where the Annual Pass gives users a twelve-month subscription payable in monthly instalments of $14.99 or by another billing plan of your choosing. Annual Pass subscribers also gain access to a new flying mount when the next patch is available to the Beta for the next WoW expansion.

The next expansion, if you didn't already know, was the once April Fool's joke-turned-real, The Mists of Pandaria, which is set to bring panda monks to Azeroth. Blizzard, it seems, is doing everything in their power to keep WoW fresh and interesting, where they're seeing lagging subscription numbers. The only downside?

The promotion only applies to current WoW players... accounts opened after October 18, 2011 are not eligible to receive the benefits of the Annual Pass. Subscribers will also not be able to cancel their account until the twelve months are up.
