Sony fortunately already said that 4K is not going to be supported on the PS4. But the possibilities for being too ambitious are too numerous not to worry about. After the last two games, that's how our expectations changed. PD was in the same situation with the PS3. They had to plan their game with knowing the PS3's hardware capabilities, and they apparently misjudged what they could do with it, even though it's impressive what they achieved with it. That doesn't make up for the obvious shortcomings of GT5/GT6. I wish they would go nowhere near the PS4's limit with GT7.
