5D Mk 2. vs Nikon D600 (Should I go Nikon?)

I've had my 5D I for a few years now, and while it's served me well through many portrait and wedding shoots, I think it's time for an upgrade. I do a few weddings and paid gigs year, but photography for me is mostly a hobby and so I can't really justify putting out $3000+ for a 5D III.

The 3 things I really wish my 5D I had are 1) better AF 2) sensor cleaning and 3) AF microadjust. The lenses that I use most are all under 135mm in focal length: an ultrawide, my Sigma 50, and a Canon 100 macro. Built in flash commander wouldn't hurt, either, since I'm currently using a 580EX to commander flashes when I want to do E-TTL off camera flash.

The latest rumors (from a few days ago) have the Nikon D600 being announced on September 13th at a price of around $1500. I don't know when it will actually be available to order, but I presume by the end of the year. If I was to get the D600 I'd probably sell my Sigma and get the aspherical Nikon 50mm f/1.8G.

Now, 1500 is close to the close market price of a lightly used Canon 5D Mark II. The 5D2 has things 2 and 3 on my list, but the AF system is exactly the same as the 5D I's. The 5D2's larger size will fit my hands better, since the D600 is said to be similar in size to the D7000.

For someone in my situation, would it make sense to go to Nikon and get the D600, or would the 5D2 be better, and why?

Well I might say. Wait to see the REAL D600 and see what has to offer, then decide..

Now answering your real question:

For someone in my situation, would it make sense to go to Nikon and get the D600, or would the 5D2 be better, and why?
It doesn't have sense to compare a Non-existent with something that do exist.

Nobody will tell you if it make sense or not, simply because the D600 doesn't exist right now.

I am also waiting to see what will happen when the d600 will be out. I guess Canon will just reduce the price of the 5D markii a bit to make it more competitive.

I dont think they will release a new cheaper fullframe body.

Is D600 supposed to be D7000's FF brethren? If it has all the functionality of D7000 along with a FF sensor, and $1500 pricing point to boot, I can see many Canonites not heavily invested into lens to jump ship to the dark side.
