This trailer announces MineCon 2012, saying sales and hotel registration for this second Minecraft-centric gathering "will start in the next few weeks" (thanks nin). Word is they are going to Disneyworld (Paris):

Last year's MINECON was held in Las Vegas to celebrate the launch of Minecraft. 5,000 people came out to play games, meet up with their friends, and have an amazing time with Minecraft fans from around the world.

This year we are bringing MINECON to Europe!
