The overall point, however, remains valid: if video does negatively affect stills at all, it's going to be negligible for the vast majority of photographers and the vast majority of images.
I am actually on the polar opposite, I wish they would take stills out of my DSLR and give me an FIT type read off sensor rather than Frame (i.e. so I can shoot 1080 50i) I wish they would give me an inverse square of HD video resolution for ease of downsampling, I quite fancy a 32MP sensor as this would largely negate bayer colour artefacts.
Or I suppose an 8MP sensor, and much larger photosites.
Yep, video is dragging the stills guys down, it's the other way about.
And after all we've given the stills guys:
You know more than I about this stuff.
By the way, Paul, I always enjoy your posts: you clearly know your craft, and write thoughtful posts that go beyond the superficial. Yours is one of the names I scan for as page through the comments.
