Good, I hope this trend continues.
The PS4 has the better hardware, it should get the better versions of games. We went through it in the PS2/Xbox days, and hopefully we'll go through it again.
I would hate for the PS4 versions to be whittled down for parity.
At least companies like Ubisoft & Square-Enix with Final Fantasy XV aren't dumb enough to make games like those on par with Xbox One.
