Should I sell my Camera Gear?

So I've been thinking about Selling my Nikon D700&D300 w/ accessories to buy a Nikon D600 & 70-200 VR II but I have my doubts about the D600 compared to the D700. My equipment right now doesn't get much usage because of school and I can't shoot on weekends because of a family situation.

Added (1). My plan was to sell both of my Current set ups to buy the D600 and 70-200 VR II

which would give me the D600 24-70 & 70-200 VR II as my Set up to use until I can afford a D800

My current set up is
D700+24-70+2xSB-700+MB-D10
D300+70-300+SB-600+MB-D10

If you want

Just wait. The D600 will be there to buy in a few years and in the mean time, you can use your other two cameras.

What do you plan to do, give up having a APS-C sensored camera? Most of us have one of each as you do now, if for no other reason, the extra reach.
