They are making a minecraft for XBOX360 and kinect. How ever there is a simular game to minecraft for the XBLA (Arcade) called Fortress Craft.
No, the XBox360 version of Minecraft is downloadable via the Marketplace.
Minecraft for the Xbox 360 costs 1600 Microsoft Points (or $19.99).
Well, hopefully not, but the Xbox 360 does have a very similar game call "Fortress Craft" which is almost the same as minecraft with better graphics. I suggest you not play it, because they totally copied Minecraft.
The official release date for Minecraft on the Xbox360 is June 30, 2012
Minecraft isn't out for Xbox360 yet, but it will probably cost something similar for it on the live marketplace.
Yes microsoft payed for exclusivity of Minecraft.
Yup
Yes
It is impossible to craft a radar in vanilla minecraft
When the update come out...
