They spoke to this very recently somewhere. Either in the Readme for P12 or the mailout, I'll have to go find that. Anyway, they said they will not require the old P11 License Key to provide the Upgrade Path. And when I registered P12 it did not ask for a previous versions key. It just went ahead and upgraded. But to even get the upgrade in the Renderosity Store I had to provide that key to show eligibility FOR the Upgrade. They even said we'd be able to go back and forth with both versions. It is expected and allowed. Yaaay! No guilty conscience! :D
