Although it is undeniable the ps4 has the superior hardware, in reality I think it makes no difference.

The majority of game devs would just make it for the lowest spec, then port it over to double their market.
Plus for the devs that will, the ps4 might suffer from the same problem as the ps3 where it was too complicated a system for devs to have the time to make the most of it, so games ended up looking better on the 360 because of its simplicity for optimization. (see red dead redemption for example)
