Groove agent 4 se upgrade to GA 4

Can somebody please tell me why we can’t upgrade from GA 4se to GA 4 really?
you would think that Steinberg would give customers that spent a lot of money
on their cubase product, the choice to upgrade their GA 4 SE (Included with Pro 8)
to the full version of GA 4. But they have an upgrade for GA 2 & 3. :open_mouth:

Cubase Pro 8
