PC is always more affordable over time.Because a PlayStation is $500 (less, maybe) at launch while a PC that could play the game better is significantly more expensive.
With this move PlayStation's selling point is 'we're cheaper up front'....and that's it. PS5 is highly unlikely to have any Nintendo gimmick that makes it unique either. It's literally underpowered hardware that gets 6-10 AAA games quicker than another platform now.
All of the drawbacks of console gaming without it's overwhelmingly best positive.
