^^^congrats, if that was your ultimate goal!
I am also contemplating on selling my canon bodies and heavy long lenses but I am in no rush in purchasing another or any other camera(mainly leica gear at this point)body/lens/accessories at this point. Picture taking is not my main source of income so I don't have the urgency on selling any of it.
I only take random things i find interesting in the street when traveling for work and just like most people on vacation, but it hurts me to see people anchored down with such heavy gear wandering the streets - weight was my main concern when transitioning to a Leica. Moving to this system is worth the purchase, I am very satisfied with the results, don't miss the auto focus system at all, burst mode, and high ISO performance. I actually find digital noise in the image appealing to a certain degree, it adds some type of grit to the image. My Leica is more than capable for the type of picture taking I like to do.
I purchased a 1Dx 2.5 years ago and three other bodies i've accumulated since 2009. the 1Dx has less than 3k clicks on it, I mainly used it for BIF, airshows and video when using it with the steadicam merlin. I was thinking of selling it and the rest of the heavy gear but I would rather keep it after the offers I've received from craigslist and the used department in BnH.
