I prefer to only have a three consoles hooked up to my receiver.... Nintendo, Microsoft, and Sony...
Setting up six is way too much.
Backwards compatibility won't affect IF I buy a next gen console from a vendor. It will only affect WHEN I buy a next gen console from a vendor. With backwards compatibility I will buy them ASAP. Without, I will wait until I am satisfied I played all the games I want to in my expansive library...
