I have to say, the game (on my display) runs at 60fps most of the time - and only dips to 30fps in some scenes in FPS mode and in some other scenes to lower than 30 when there's really A LOT going on at the same time. A good way to test the framerate is to rotate the camera angle and see how smooth (or not) it moves (right analog stick). It's easy to tell when it runs at 60 and when it doesn't. It's not stable constant 60 as I would have hoped, but pretty good none the less and I'm glad it's in, even if not all the time.
Guess the problem is that there are so many ways to play MGS4 - if you play it as a shooter, you're bound to have more framerate fluctuations (lots of action) going on. If you play it more like a stealth game, you can keep it up at 60 fps most of the time.
