If the 9th gen consoles launch with BC in 2020, is there any reason to produce 8th gen consoles beyond 2020?

So you don't believe that 8th gen consoles will be considerably cheaper than 9th gen consoles when they launch?

Nothing is confirmed yet, but it's very likely microsoft is launching a cheap 4TF disc-less console for $250-$300 and a more expensive 12TF version with a disc-drive for $500. So for microsoft is should be no point to keep selling 8th gen consoles as they won't be cheaper.

But for Sony PS4 should be about $100 cheaper than PS5, maybe $150 if they do a super slim version.
