I have some difficulty understanding your point with this. If you are satisfy with the 5D Mk II, I don't see why you would buy a new camera anyway; lenses seem like a best investment in my opinion. It seems the 6D is aimed mostly for people who wants to move from crop sensor to FF but are on a budget, just like myself. I personally shoot in manual focus about 99,9999% of the time, so the number of cross type focus point for the AF passes well above my head. The fact is that in term of image quality, both 5D Mk II, Mk III and 6D are pretty similar because it is the lens that matters most. I can see much how the 6D is so pathetic; yes it is less robust, as a less effective AF, etc. The 5D Mk III is there for a reason. However, I rather save the few hundreds bucks and get myself lenses (or food). Also, the 6D as a 97% VF, the 5D Mk II as a 98% VF... I am not sure how the 1% lost is going to affect you, but for myself, I guess I could live with it, especially since the 6D as better ISO performance. The Wifi and GPS don't interest me all that much; however, the great thing is that they can be turn off if you don't want them (although the Wifi can be really nice for studio work and maybe with future update, be used as intervalometer). Lastly, I most say I am disappointed to see so much people bashing and fighting about sensor and camera, I feel like I am in high school again, with people insulting each other because they don't like the same things. In a forum about photography, I though people would speak more about the actual art, and not about what piece of gear sucks. The tools we use are not that important; I should say barely important. If the camera becomes more important that person holding it, we are not photograph anymore, but just image takers.
