I was flipping through my September 2005 issue of Sound & Vision, and they have a multi page article about 1080p in regards to the new Mitsubishi WD-52627. The article starts on page 38, and on page 40-41 they talk about 1080p vs. 720p
In the end they state the most of their first looks in a side by side test with a 720p display next to this 1080p display, showed little improvement at all. They switched to a Discovery HD show and that is when they finally saw a better picture. It wasn't much, but it was a little better in regards to text, and a computer illustration. They said that the display was good at it's 52" size, but 1080p really would be better in displays larger than this as the added resolution will really help in the larger images so that they have more data to feed the larger screen.
Also, they noted that this "cutting edge" 1080p TV really does NOT have 1920x1080 resolution, but has 960x1080 resolution (only half of real 1080p), but uses "wobulation" (TI calls it SmoothPicture) which is actually an optical actuator that moves the set of mirrors that make up the 960x1080 field, back and forth alternating images reflected on this mirror field so that it is able to shoot half the image every 8 miliseconds.
They say that it is not noticable to the human eye, but almost sounds like 1080i, but at a killer refresh rate. I know it is different, but this MAY be how all 1080p devices are at this point, so take it for what it's worth. They question if it is worth the price, but for someone who does not have a nice HD display, and who wants to be a little more "future proof", the premium cost might be acceptable.
Good luck!
