This is very frustrating to me because I cannot decide if I should go with the 800u or 85u. 24p is a big selling point, but only if properly addressed. I don't want to pay a $500+ premium for a gimmick and a few extra speakers.
yes you are, as long as the frames are displayed in ANY multiple of 24, the 24p implementation will be correct, 48, 72, 96, 120, etc. It's a simple enough concept to implement, just double every frame you have received...now how well panny does it (i.e. is there any increased flicker because of the lower than 60Hz refresh rate, do they try to "better" the image by doing some interpolation rather than just a "pure" frame repeat, etc) we have to wait and see.
check out the main 2008 panny thread for detailed discussions on the 24p implementation
EDIT - I am also trying to decide between the 85u and the 800u and if it's worth the extra 500 or so. The 5120 greys of the 800u will be one big differentiator imho. I am not sure how much diff the 2:2 24p will make (i.e. as much as the 5120 greys) since that only takes care of uneven cadence (3:2) judder but the inherent judder in 24p material still remains. In all the 60Hz plasmas I have seen so far running blu-ray demos I have not really "noticed" any judder. We have been seeing uneven 3:2 cadence for a very long time with regular NTSC 60Hz displays (because of the telecine process of 24p material) which has made us quite used to it, plus each individual's sensitivity to judder will vary. I am likely one of the people who isn't bothered by 3:2 judder in 60Hz progressive displays. I think many will find that is the case. But I'd still like to do the ultimate test - Wait for the 800u, demo a slow pan shot of a 24p blu-ray at both 48Hz and 60Hz on it and see if I can tell the diff. If I can't then that confirms that I don't need it and the only diff to me is the 5120 greys. That is if I can be patient long enough without succumbing to the 85u

panny will do 48Hz (2:2) and not 96Hz (which would have been 4:4 frame repeat). the 800u manual has confirmed this.

apparantly pro pannys (2007) already do 48/96Hz, it's not a new 2008 feature.

imho the only advantage the panny has over the 4280 is 1080p vs 720p, in everything else the 4280 tops the panny. so if your seating dist is far enough that 1080p offers no advantage (see the article in my sig) go for the 4280.
