Well I just got a setback from Adobe's Buying Guide:
You cannot upgrade from products within a suite edition to individual products. To get the latest version of an individual product, you must purchase the full product.
That bumps the upgrade price for me from US$179 to US$399 since I own Production Premium CS5. I'm still planing on at least getting the trial. Hopefully nothing's removed from it aside from the CC effects.
It looks like you're new here. If you want to get involved, click one of these buttons!
