Panasonic is replacing the HPX600 with the HPX610. I'm not sure what the differences are, but Panny will stop production of the 600 at the end of September.

You can also trade in your 600 for the new PX800, which is a 600 body with three 2/3" CMOS chips and AVC/Ultra.

FOR SALE: PANASONIC HPX600 / Fujinon XA17X7.6 BERM...

I have one AGHPX600 with color viewfinder and Fujinon XA17X7.6 BERM M6D lens that I purchased new in May, 2014 and now need to sell ASAP. I'd be interested in selling the body or lens separately as well. If you are, or know anyone who might be interested please let me know...it will be a great deal since there is under 150 hours on the camera.
