We're thinking now that the space in our HT room designated for the display can maybe
squeeze a 60" HDTV depending on whether or not the sides can come out a bit and clear the cabinet doors to the left and right (the right side cabinet holds our AVR and BD player).
Unfortunately, our seating distance absolutely cannot change -- it must remain at 12 feet or so from the display to the main viewing area (basically my spot).
The wife has been liking the looks of the Panasonic plasmas at 60 inches, while I think I'd prefer an LCD set (actually, what I would prefer, between you and I and the man on the moon, is any one of the 72, 75, 80 or 92-inch DLP Mitsubishis that are out now...but that's saved for a fantasy when I make more money or win some kind of lottery) if only because of the 120/240Hz refresh features that turn film into a video look (don't ask -- I know I am in the minority on this one...).
No matter what technology we end up going with, will we see a drastic viewing difference moving from our 50" Sony SXRD RPTV to a 60" screen? Keep in mind our viewing distance absolutely cannot be changed; will we see at least some
dramatic differences going up 10 inches in size?
