I'm not sure how "available" next gen consoles are atm. I managed to get a ps5 3 months after release and that was entirely through luck. Maybe availability isn't helping with dropping pre-gen consoles.

AAA games are stagnant because they don't set trends anymore they merely repeat what worked in the past with a shinier coat/ recycle ideas from indie games that have done well. they're not unique and graphics can only do so much to help a game.
