All that happened was the rebate expired on Sept 30. Canon has already re-upped the rebate here http://cinemaeos.usa.canon.com/promotions/#c100
BH and adorama probably just haven't updated their websites yet.
Saw the film in Canon's theatre at NAB today. A couple of things. I felt the grade and the lighting were a little (maybe a lot) over baked, certainly for something that is essentially a camera demo. Not at all indicative of what we saw from the camera in the demo booth. Regarding the dp not having time to test, that's not true, they did extensive tests with the camera prior to shooting. I think perhaps though that there wasn't time to do a nuanced grade. That on top of the script and the acting made this film a disappointment.
As for the camera, I went back to the booth 3 times during the day and got a good look at a lot of gamma's and looks from the camera. Color rendering seems quite improved, and frankly a new outlook. Skintones have a decidedly "alexa" look and the highlight range on this camera is a thing to marvel at. It was really hard to get the skin tones to clip even when we'd overexposed the shot by 3-4 stops. At a "normal" exposure I panned up to the lights on the "jungle" set, and there was full detail in the lens and housing of the light. The only thing we saw that raised an eyebrow was some nasty pattern noise in the deepest blacks in the image....visible at virtually all iso's. This "could" have been the monitor, and the canon guy didn't have an answer for what was causing it other than..."this isn't the final camera". Realistically this would be crushed in the grade most likely, but I really doubt canon would release this camera with a problem as glaring as that....and...for what it's worth, we didn't see any unusual noise in the "Trick Shot" film on the big screen.
