Minecraft for Kinect is an XBL

More details have begun to trickle out on Swedish developer Mojang
Studios' first Xbox 360 title, a Kinect-enabled port of indie hit
Minecraft. Beyond the fact that it'll be some form of indirect port and
that an unnamed developer other than Mojang was at the helm, few other
details were known, but as Minecraft creative lead Markus "Notch"
Persson revealed on his Twitter feed last night, Scottish devs 4J
Studios are apparently in charge of this holiday's world-builder.

If you, like us, are unfamiliar with 4J, a cursory Wikipedia'ing reveals
work on a wealth of ports, not to mention a handful of
not-so-well-known original games. Hopefully any worry you have in the
studio's confidence is abated by the fact that Notch will remain a game
designer on the project, presumably retaining creative oversight.
