Why do you want to update? If your present camera does not do want you want it to, then start looking. Both cameras are the best out there. If your present lenses will work on a newer body, then stick with Canon. Why buy new lenses, depending upon what you have now. Read up on what is available. It all depends upon you, how serious you are and what type of photography you want to do. Have fun. It is only a hobby.
Looking to upgrade because the Canon XT has AF probs and the 18-55 kit lense is just a hair above mediocre.
