The hype continues for Diablo III, but if you really want to be ahead of the curve, you gotta be excited about Diablo IV! According to III's designer, while the plot of the upcoming game finishes off the trilogy and ties up loose ends of the the first two games, it's not the end of the Diablo line.
“We’re not saying this is the end of the ‘Diablo’ universe, but we are trying to bring this storyline to a close,” Lead designer Jay Wilson said. “It’s not just ‘Diablo III’ — we’ve got plans beyond.”
Blizzard's PC/Mac RPG Diablo III comes out "when it's ready," and Diablo IV comes out in the speculative future.
