I think it depends. This will probably be true if PS6 is an outlier in price in its generation. But from the way it looking, PC gaming is also just going up in price and a xbox will probably be somewhere in the ballpark, almost all due to hardware prices. Ive read rumors the next gen xbox is speculated to also be in the $1,000 range and its pretty much known that valve wanted to do around $800 for the steam machine, but hardware prices made that non-viable for their scale.

I think it'd b more accurate to predict that people won't just give up on the ecosystem, but gaming in general. Or more people will just move to gotcha phone games.
