What's the difference between "hard" and "crushing" difficulty?

While watching videos of "Crushing" difficulty on Uncharted 3, (see my answer to this question, although beware of spoilers) I noticed that it seemed like there were no button prompts during the QuickTime Events. I've never played an Uncharted game on Crushing. I expected it to take less hits to kill Nathan, but is this lack of QTE prompts also a feature of Crushing difficulty? Are there any other differences between "hard" and "crushing?"

Increased enemy health and accuracy, decreased health for Drake (or at least he takes a lot more damage!) are the main differences. I don't think spawn rates are affected but they may be.

Treasures, puzzles and general proceedings in the game remain the same, and I'm pretty sure the QTEs are still there (no source though - haven't played it on Crushing myself yet)
