Blizzard's COO Paul Sams spoke with Gamasutra the other day, and he called out Microsoft, of all companies, for not supporting innovation in PC gaming. He says that Microsoft's loyalties are split with their console business, and that if they put as much work into developing gaming on the PC as they did on the Xbox 360, everyone would benefit.
An interesting idea, to be sure. It's not like Blizzard necessarily needs help from Microsoft to promote and develop their games -- if anything, it's Microsoft that could probably take a lesson from Blizzard on how to release software. But it's true that console innovations like achievement points and Xbox Live social networking accounts aren't really finding a solid place in the PC gaming world, and it could be that Blizzard wants to see those types of things on the platform.
Blizzard has always had a rocky relationship with consoles anyway, and the recent announcement of a non-console Diablo 3 definitely shows they're interested in the PC (including Mac) platform only. Can't really blame them for wanting a little more love from an OS developer like Microsoft.
