Apple smartened up.
enclosed in my bundle of FCS2 was "upgrade coupons" for any future FCS release at the academic level.

only minor downfall is I'll be out of school by then most likely, unless I go to grad school, but nonetheless its a nice gesture on apples part

How much does the upgrade cost?

hee! Apple have routinely included coupons with purchases of the various OS's over the years ... don't think I have ever seen any offer that has allowed you to actually use them.
