@Stubi: if you're into press photography, I'd suggest you go the way of 1D4. For one thing, the extra FPS means the difference of having the shot or not having the shot; the other thing - shutter life (150,000 vs. 300,000). Of course, the extra crop factor allows you to get more distance out of your lenses.
Of course, the 1D body can take more beating than the 5D2 (especially when you're fighting for position with other press photographers/camera people, there's going to be a lot of pushing and shoving).
