I just heard from a friend at NAB that Panasonic will NOT upgrade the HPX600 to AVC/Ultra. He talked to the development engineer for the 600, who said it will never get an Ultra upgrade.
Never mind that it was always advertised as being upgradeable to AVC/Ultra.
That really sucks, as it was touted by Panasonic as the first Ultra camera. I'm glad I never bought one. I feel sorry for those of you who did.

My next camera is a Sony.

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.
