I'd say you need to have some specific feature you want to have which you can't have without switching cameras. To weigh your cost of getting that feature, include the "loss" of your present lenses and your learning curve in moving to a different menu format and camera controls.
Might just stick to Canon and maybe go with the SL1 since I do have a couple canon lenses.
