In addition, Collector’s Edition owners will receive an exclusive in-game skin based on the physical Metal D20.".

Salo also confirmed here that the free Digital Edition upgrade would be applied for Early Access players on 28 August.

Interestingly, there's no mention on the latest CE website of the the 72 early access being just for act 1, which I'll admit always seemed something that it would be unnecessarily tricky to implement. I have my fingers crossed that we'll simply get access to the full game 72 hours early even though I doubt I'll get through all of act 1 in three days anyway!

Perhaps we'll get a definitive steer at the next PFH in July.

Thank you, seeing the reply from the Community Manager has assuaged my fears for this.
