If you have a Mark II there's really no reason to upgrade, but if you're shooting anything else, now's the time to take the jump.

Not to add more fuel to the nikon/canon fire, but selling all my lenses and nikon bodies in favor of canon was the best thing I ever did. Nikon's in camera color handling is a fucking nightmare.
