Adam,
I just purchased the HPX 3000 last month. Just completed production on a 30 minute dramatic/training program and the results out of the box were pretty impressive. Although we did not use AVC-Intra (at that time FCP did not fully support it); the DVCPro codec coupled with the full raster 1080 image was a notch above the Varicam. I have been a Varicam owner since 2002 and also have the Panasonic 900.
Workflow is the big issue but I believe that once clients understand the process it will become much easier to transition into the P2 world. I was able to ingest over 9 hours of raw footage into our FCP suite in less than 6 hours.
The camera’s dynamic range is remarkable and I feel that I have not even begun to tap the full resources of the 3000.
