I called Adobe support about this and they verified that purchasing this at my school for this price would qualify for free upgrade to CS6. I figured I'd update the question here in case any other students are in the same situation.
I'm also in the same situation, kind of. I already got my cs5.5 master collection through my school on the 26th. But every other post I've read about the upgrade only says Creative Suite cs5.5 will get upgrade. So I'm trying to find out if people who got the master collection (which comes with the Creative Suites) are eligible for upgrades complimentary? Any help answers would be appreciated. Thanks.
Creative Suite comes in a variety of packages, of which the Master Collection is one. See http://www.adobe.com/products/creativesuite.html for a list. So, yes, Creative Suite 5.5 Master Collection is eligible for upgrades under the same terms as the others.
