Yesterday evening Blizzard put new job offers online. Ok, that’s nothing special but this time they all start with :

“ The team behind Diablo I and II is looking for a skilled ….”

Why should be mentioned that the team behind Diablo 1 and Diablo 2 is looking for new staff members if the project they are working on, has nothing to do with Diablo? This seems to be one of the strongest hints so far that Diablo 3 is already under development.
Blizzard is looking for a Lead 3D Level Designer, a Senior 3D Level Designer, a 3D Level Designer and a Associate 3D Level Designer as well.

Some people are speculating that the first information about a Diablo sequel could be revealed at the upcoming WWI. One reason for that is that Blizzard will only permit entrance to WWI, for visitors above the age of 16.
But neither the WoW Addon, “Wrath of The Lich King” nor “Starcraft 2″ are containing material which would justify that sanction. Draw your own conclusions.

Tickets for the Worldwide Invitational 2008 will be available next week on Blizzard’s official WWI Website.

Tickets are on sale now.
