One of the biggest missed opportunities in console gaming is BC will all prior generations. On PC you can buy a game on Steam and know it will run on a PC 10 years from now. With current gen consoles being based on X86, if Sony and MS stick with this architecture, is BC a given without having to have a miniaturized PS4/XB1 included in the PS5/XB2 box? Can BC be handled like PC where things just work due to being on the same architecture, just upgraded?
I know people say that BC isn't super important in the long run, only really in the first year. That may be true to some extent, but it would be better for Sony and MS as far as customer retention goes if they can guarantee BC for future consoles. People will have an incentive to stick with either line in the future and not defect to the other. It also makes buying into DD a lot easier, knowing that your purchases will work with future hardware.
