Though there's little to no clarification about the changes, it seems that the different versions of Vegas Pro have a character quota and with the perpetual versions that character quota is much less than with the subscription versions. Thus far, there doesn't seem to be any guidance about what happens after the quota has been used up; for example, will it be that an another character quota needs to be purchased? And the My Profile in T-t-S is still not not accessible.
