He wanted a break. I would have taken a break too. He is loaded now, has a wife. He wants to go enjoy himself with his family. You have to understand that, I know we all love him, but let the man get some rest. He'll be back soon.
Didn't quit, just stepped down as head coder of Minecraft. He's still the head of Mojang in itself, he's just focusing more on Scrolls now. Besides he'll still be coding for Minecraft, just not as much as he was. Jens is head of coding for minecraft now, and I assure you we're in good hands.
