Played Uncharted 2 last night and.......THEY'RE RIGHT!
The cutscenes (but you can't tell they're cutscenes because they use the game's engine) are HD FMV's! I went back and watched some of them using the options screen. I said to myself, "Damn, these things are loading fast!" They shouldn't be able to load the environments, characters, and such in less than a second! They had to be videos.
The thing that really gave it away was the character skins. I'd be playing as Doughnut Drake or Chloe, and right in the middle of gameplay, they'd turn back into normal Nathan as something spectacular was happening, and then turn back into Chloe or Doughnut as soon as it ended.
With the amount of FMV and bonus cutscenes (at HD resolution, too), I know the 360 couldn't hold it all on one disc.
I was wrong.
