I think thats a bit of a stretch. I would predict we'll see overall higher framerates, definitely better AA and AF, and maybe slightly better shadows and resolution? I'm sure it will really come down to what the developers as willing to put time and money into. It always does.
Once again I predict we'll only see the real difference in exclusives...mainly FP exclusives...mainly Sony FP exclusives...mainly games developed by ND, GG, and SSM. lol
In all seriousness, if I had to make a bold prediction, I was say the difference this time around when it comes to FP exclusives, the gap we'll be wider than last time. Mainly because of Durango's rumored OS overhead and Orbis's rumored overall advantages. Just like SS fusion Gogeta, Gotrunks, and Vegito. lmao
As i said some. But what you say is true. It will be mostly like you say. 1,3 to 1,9 is imo big difference. 600 Gflop is not small. It is more than PS3 or X360 can achieve.
