Camera bodies come and go very quickly, lenses are forever. If your not making any money off your camera, i'd use a hacked gh2 over a 5d, the camera body costs 600 bucks or so and the image quality when hacked is ridiculous, it won't hold you back and you won't have to jump through hoops processing raw data etc. You'll be grateful you spent $3500 (spend it on lenses and accessories instead!) less in 12 months time when some other camera is the hot thing.
In a blind test, Francis ford coppola actually picked gh2 footage as his favourite footage over red epic, arri alexia and other pro cameras, some of which cost as much as 75k.
In a few weeks we should know whether the Black Magic Design Pocket Camera arrives on time or not, that would be a much smaller investment and a good upgrade in image quality with raw/prores shooting.
