As mentioned the Panasonic's have an anti glare coating that seems to work well. When I was in Best Buy this weekend I couldn't catch any glare off the Panasonic sets, unfortunately they didn't carry the Pioneers in my closest store so I'll have to see when it arrives.
My old Toshiba Plasma does catch some glare during the day off the side windows, and during the evening with some of the interior lights. I don't find it to much of a bother, hopefully the new Pioneer will show some improvement in that area.
