No, he said F7 reflections were 30, and GT had some at 60 and some at like 20. I'm a bit surprised he didn't mention how cruddy the GT reflections look, though. Very pixelated.
Just watched the beginning again, he says that it's the PC version with all settings maxed out at native 4K and other than some things like reflections in mirrors being 60hz it should be the same as the X1X so I'm guessing the X1X is going to have 30fps reflections in mirrors.
