As Nick says, just take a step back for a short while. Your speculation is running riot and is largely incorrect.
News will filter through soon as to how things will be and it's not all bad.

Out of interest I just had a look at the Denon download area for firmware. There's some pretty strong warning on there guys!.

DENON recommends you to update your unit only in case where some problem has been encountered. To update the firmware of your product feel free to contact the authorized DENON-retailer where you have purchased your DENON product. Phone number and the address of your retailer you can find on here

Do they still support 10yr old product? 15yr old product? 20yr old product? ... Er NO!!
Are they still developing firmware for any obsolete product? ... I don't think so?

Anyway, as I said, just hold on for a short while and more information will come through.
