Did you just say "Plus, cam corders still mostly use VHS."?

I have yet to see (outside of store displays) one that does not, except for models that don't record at all but only transmit to another device that does the recording (e.g., via firewire to a computer). There are also security-oriented video cameras, but those really are a different market from cam corders.

And according to wikipedia, analog camcorders aren't even marketed anymore

Aren't actively marketed with TV advertisements, perhaps. It is certainly still possible to buy one, although frankly at this point almost everyone who wants a camcorder has already had one for a while, so new sales in the last couple of years account for only a small percentage of the total units in existence. If you don't happen to have one, it's also not hard to go out and rent one for a week (unless you're trying to rent it for the week of Christmas or high school graduation, of course, in which case forget it). New sales at this point are mostly to young people who just moved out on their own, so it takes a few years for a new model to gain siginficant share.

DVD camcorders are currently the fastest growing market segment.

Now you're making my point for me. DVD camcorders are still at the stage of being the fastest-growing market segment for new sales. This implies that they're the new, up-and-coming format. In a couple more years they will dominate new sales to the extent that their market share can no longer grow much, and then in five or ten years after that they will account for the majority of the units people have. Nothing that comes out before then has a prayer of gaining significant acceptance in the market, because DVD has the mindshare. DVD isn't ready to be the old format on its way out yet; it's only just started to really get going.

You may be confusing 'video cassette' with VHS. VHS is a specific form factor and encoding standard of tape. 'Video cassette' can refer to MiniDV or Digital8.

(it's similar, although not entirely like, referring to a DDS tape as a DAT -- they're the same form factor, and the earlier versions could be read in both types of readers, but they're no longer compatible)

Oh ... and I bought a MiniDV camcorder three weeks ago. (the video's fine, but they've gotten these things so damned small that the mic is too close to the tape mechanism, and the audio is just foul) ... and I moved 'out on my own' many, many years ago.
