It truly depends on what you want or need to do with your camera. If you need quality photos shot in low light with motion, get the 5d. Otherwise, keep the 60d and upgrade your glass. The 5d2 I mentioned in an earlier post belongs to my boyfriend, so I get to shoot with it if he isn't using it. I decided I couldn't afford the 5d2 plus appropriate high quality glass, so I purchased the 7d and 17-55 f2.8. It is doing a superb job for weddings, portrait, boudoir, fashion or anything else I point it at :-) I kept the Rebel as a backup. Quite frankly, my clients can't tell the difference. A mother of the bride that booked me last weekend mistook a photo that I shot in a Wal-mart restroom with an Olympus E-PM1 (budget mirrorless if you're not familiar with it) as being a wedding floral shot taken with one of my dslrs. Photography is not all about the gear. If your 60d meets your current needs, get some great l glass which will hold its value and be there when you do need to upgrade.
