I don't really understand this decision. From an experiential standpoint, the Rift seems like a pretty obvious platform to have a release of Minecraft available. Within a short time it will likely have a solid user base which makes it a good business decision as well. Now support for that platform is being pulled, not because of any technical, financial, or licensing issues, but because Notch thinks the new owner is creepy? That seems like a knee-jerk reaction drawn more from emotion than logic.
