This will sound like a question from a Canon fanboy (I realize my signature doesn't help any as well), but why are you switching? If you have a decent Canon body and a few lenses already, you could use the money you are looking at spending on a new body/system and put that towards a great lens. As much fun as it is getting a new camera body, for me at least, lenses have always spurred creativity and opened doors far more often than body changes.
