Tired Tyres
No, we need GT6 for PS3 with about 300 premiums as PD can make about 50 a year.
(with say 25 upscaled missing tracks)
They can make more cars, because they increased the staff and optimized their process.
And GT6 will be released in about 3-4 years. They will bring on PS4 like it or Not. Yama complained about the PS3 Specs already. They can Add everything per DLC or Patch. They dint Need to make GT6 a PS3 Game and they have the Time to do it.
2013-2015 will be the years of the next Generation console. Sony would be Totally stupid to waste 50,000,000-70,000,000 for GT6 on PS3.
They can use the GT5 Engine and save some Time. They just make some improvments.
Dice Claimed already that the Frostbite 2 is "Next Gen ready"
All Engines nowadays are Based on Multi core and massiv Theads structure...
Upscaling will Not work on the PS4. PS2 content on PS4??? That would be a epic fail...
They will use their higher modelled Cars and integrate them in GT6 and some per DLC for GT5. The can Decrease the quality to fit it in to the PS3 Hardware.
A Developer Producer their Content in higher quality than the ps3,360 can handle.... Often
Some Things arent possible on ps3 and GT6 Needs huge improvments....
Like up to 64 Cars on track in Good quality for better and realistic Race Series and endurance races.
