Well, I was looking closely at the tubes, and the 4:3 HDTVs all seemed to use the style of tube that has the red, green, and blue phosphors lined up in columns of all one color, Trinitron-like. That would definitely support 1080 lines, but the dot-pitch (or aperture grill spacing, more likely) wouldn't support a large number of horizontal pixels. But, then, maybe HDTV has analog lines, like NTSC. Doubt it, though. Anyway, I didn't have a loup with me to examine closely, but the AG spacing seemed to be about the same as on the NTSC sets. It still looked nice, but, nonetheless, I worry that they've just put a new yoke on an old tube.

Good point about the manuals, too. Thought about it after I posted and tried to find some on the web. Couldn't find anyone's. Guess I'll be going back. Maybe this time I'll go to the upscale shop. I don't like them so much, though, because they've already decided what I'm going to buy, and as such, only have those few sets on display.
