Blizzard is looking for a "lead game designer" who (according to the official job posting) can "help lead the team that designed Diablo and Diablo II." The posting also notes that experience working on RPG titles would be a plus. This has lead some individuals to speculate that Blizzard is beginning to ramp up for the development of Diablo III.
What we really want to know is this: will D3 be 3D? Isometric is so 90's!
