Determine what you want. Then buy it. Do you want a 1DX? I do. So I am saving up for it. If you want a 6D, buy it. If you want a better camera, buy that. It's just a matter of too much choice. If Canon only made three cameras, it would be so much simpler. Sounds like you are going to buy the 6D, and maybe later you can get a 5d when they are closing them out. In this day of sensors, and no more film, it's only the lenses that hold their value, sadly.
