Thomas,
It's far worse than just the effects of a mere consumer
HD camera, that would be child's play compared to what's
coming. The new Foveon X3 imaging chip cameras are being
hyped as being capable of going beyond HDTV standards at
a lower production cost per chip than conventional CCD's.
The real limiting factor is the match between the signal
input limitations of display devices and the amount of
signal quality increase that camera manufacturers are
willing to invest in before it becomes a waste. HD cameras
are already there, a normal TV cannot display the increased
quality of it's signal. Foveon chip cameras may go beyond the
new HDTV 720p-1080i TV broadcast standards.

However, the Foveon chip cameras and your consumer HD
camera are both still "Pie in the Sky" right now.
There's no reason to put off any purchases needed to
cover current video gear requirements, but I would
keep a close eye on the trade publications for the
next year or so.

That's not really news.
There are conventional CCDs already used in digital still cameras that
exceed the resolution of HD. They're not interesting for video, simply
because it's not arbitrary resolution that of interest for video, it's
standards that are of interest. There are also pro-class digital
film-replacement cameras, the stuff Lucas uses, for example, that go
beyond HD. Again, not terribly interesting if you're after video.
The current Foveon X3 chip is about 3.5Mpixel, certainly better than
the ~2MPixel for HD. Great, but not interested in video terms. What
will be interesting about this chip, assuming it can keep up with a
full 2MPixel+ at 30 or 60fps, is the simple fact you get RGB in one
chip, rather than the need to go to separate RGB sensors, or
Bayer-pattern filters. The CMOS technology, too, is interesting, as
that's GUARANTEED to cost less than CCD, once it's mature, anyway.
Another thing that interested for video work, even in today's cameras,
and hasn't been covered well in the press, is the fact that the X3
chips can effectively merge quads of pixels as one -- so you can run
at 1/4 resolution with 4x the sensitivity (2 f-stops). This could
makes for an excellent DVcam/Digital still combination.

Sure, but again, not news. You can have this already, for a price. You
don't see consumer cameras doing this, and won't, simply because
consumers need standard formats, not something weird.

The interesting thing, to DV fans, is the realizaton that HD MPEG-2
runs at rates slightly below that of DV. So it's easy to envision a
next-generation camcorder that does DV, super-long-play
DV/DVD-resolution MPEG-2, or 60/90 minute HD MPEG-2. With Sony already
pushing the microDM format (which won't hold any reasonable amount of
HD-rate video), MPEG-2 editing support will grow, fast.
Another future consideration: new formats. There's this band of
consumer electronics companies pushing for next-generation blue-violet
laser DVDs with 27GB/layer capacity. A 3" disc using this technology
would work nicely in a camcorder. And there's the existing DVD
consortium, talking about a next-generation HD-DVD using the same
storage, but more modern encoding techniques (they're saying MPEG-4,
which isn't really suited to that, but there are other encoding
schemes, such as what On2's shipping today, that could deliver this),
so you can fit more video of the same or higher quality in less space.

I intend no rancor or malice in the above statement. I just
wanted to see how many times I could use variations of the
word "interest" ( I did it again ) before it became too
awkward :-) But, I'm beginning to lose interest ( and again )
in this subject.
