New product launch?

IMO it should be one fixed price for all current models. Buyers of more expensive models already paid for the premium at initial purchase. The D-Premier should not be eligible for an upgrade since that was officially upgradable for a limited time only. For the OdA the upgrade should be 'free'.

Of course Devialet being Devialet will probably think of something else to generate more revenue.

That's a bit unfair on D-Premier owners 

Essentially that means you are forcing people to do each and every upgrade, as if the criteria is that you are only allowed the new upgrade if you did the previous upgrade then you are forcing people to pay each and everytime.

I do get that people who did the previous upgrade should get a different upgrade cost than those that didn't - that makes more sense, but Devialet aren't the best at "makes more sense"
