Given the popularity of World of Warcraft, StarCraft and...Diablo III(?), millions of people spend a lot of time using Blizzard's launcher. If you're one of them, you might want to check out this video, showing the new, updated version of it.

There have been screens floating around for a few weeks now, but this is the first video I've seen of it in action. As HuskyStarcraft says early on, the biggest and most important thing is the centralisation of the whole business, turning it into basically Blizzard's version of Origin.

Plenty more details in the vid though.
