RX100 vs. old D70
I have ended up with the RX, and OMD, a D7000, and D700. Going to keep the 700 and RX for sure.
I am thinking along those lines as welll - RX100 to carry everywhere, & the D600/700/800 for those times when I need the ultimate quality & responsiveness. I already have the RX100, but for the other one, I am going to wait for all the September announcements.
