No, the XBox360 version of Minecraft is downloadable via the Marketplace.
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 it will you will be able to connect to the same servers as on the PC version.
Yes microsoft payed for exclusivity of Minecraft.
No it doesn't not even pc or ipod edition it is considered a myth in minecraft. I know this because i asked the same question.
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.
Yup
Yes
Same way you get minecraft on any computer download it.
No, they won't generate the same terrain. Seeds stop 'working' every time a version changes, as new things are added. There's no way a PC seed will give the same thing on the XBox360 version.
When the update come out...
