Adobe could offer an upgrade path to those who have 1 version prior only. And announce that it will be all cloud in 2 versions.
Adobe could sell a perpetual lic only to individual users.
Adobe could sell a perpetual lic on installments like the cloud and after 2 or 3 years give you a code to perpetualize whatever build you have.
Adobe could have both ditribution modes like auutodesk,Maxon and intuit. money is money ( maybe forcing upgrades through price structure.
Any combination of the above.
The line that they only make money with the so called cloud that really isnt a cloud is totally B.S
