>>I can't find anything indicating that if I bought FCS2 Student Edition that I couldn't upgrade it? Anyone have a definitive answer on this?<<
While this applies to upgrading TO FCS2, with rare exception, it has long been Apple's policy that Academic versions are not upgradable.
From Apple's FCS 2 webpage:
"The upgrade version requires a valid serial number from a commercial version of Final Cut Studio, Production Suite, or Final Cut Pro 1, 2, 3, 4, or 5. Academic and not-for-resale versions are not eligible for this upgrade."
