While I think both 8th gens should have had better GPU's at launch, so I see the need, but I don't think it will do much. I think most developers will not make that much of a difference.
Think about it, you can design a game for 30 million PS4 users, or say 3-6, and I'm being generous, PS4.5 users after the first year. Which market would you target?
I think it will mostly be exclusive that take advantage of the slightly more powerful console.
