Please help me understand why people are excited about 6D? I cannot be excited about 97% VF, 1 x-pt AF, crippled 6D with wifi and facebook buttons. I will stick to a 5-year-old beloved 5D Mark II which is identical in IQ to Canon's newest sensors. Canon, you are not getting a dime of my money on your recent cameras. I have diversified my lenses so am not hostage to inferior sensors anymore.
But i will switch to Nikon. Where i live the difference between Nikon D800 and 6D is around $500, the Nikon D600 is cheaper than 6D.
All the best with your switch. In some countries, 6D is more expensive while in others just like ours, it's cheaper. Just remember that you also need to switch lenses. It should also be expensive to switch unless you're still not yet invested in Canon lenses.
