Sorry about the OT post, but I had a couple questions about V3 and licenses.

1. If I buy a V2 student license now, can I still upgrade to V3 for free when it comes out?
2. What's the difference between the student version and regular version? Are there any license restrictions? (e.g. can I still use it when I graduate, and what about upgrading to a new release from an older student version?)
3. Will there be a student version for v3?
