Dual Entitlement Question

Quick question on the digital deluxe edition and PS4/PS5 dual entitlement - if I start playing 21 on PS4 and later switch over to PS5 does my progress follow me to the new platform?

Yes it should. It's tied to your PS+ information, and your local save files need to migrate for your offline stuff.

The PS5 is not real.
It is joke promoted by Ramone and those in power.

I have yet to see a PS5 in the wild.
I will see Kevin go 12-0 in BR before I see a PS5
