Who knows? There are still people who say CRT is the best display hardware and LP the best music software.
At this stage of rapid technological development and hence rapid obsolescence, maybe it is better NOT to look around and enjoy what you got unless you, like many here, are middle class av enthusiasts. With 3D coming, it may be the best time cost-wise to look for a 2D TV in coming months.
Seriously, with no 3D broadcast announcement from local broadcasters/cable TV providers and dearth of 3D movie/concert software, patience is a virtue. Even when 3D is everywhere, it may not be the best policy to buy the most expensive 3D hardware given the rapid obsolescence these days (OLED, deep colour, glass-free 3D, resolution higher than 1920x1080 not to mention other unexpected invention/crisis).
