World of Warcraft expansion packs, two StarCraft 2 titles and Diablo 3. Tippl also pinned a Diablo 3 expansion as the possible sixth title. Blizzard said it is immediately focused on updates for Cataclysm, releasing Diablo 3 and finishing StarCraft 2: Heart of the Swarm.
It would satisfy our OCD if these six games would release two-a-year at six-month intervals for three years, and it would satisfy our ADHD if all six titles dropped on the same day, but Tippl didn't provide any more specific dates. Titan, the mysterious next-gen MMO from Blizzard, wasn't mentioned, but it's not a "proven" property and could still launch in its rumored timeframe of late 2013.
