1080p an issue for now?

Just did a side by side comparison of lcd, plasma, and rear projection technologies at best buy. LCD definitely had the best picture, followed closely by plasma. DLP and lcd rear projection weren't as sharp, and being even a little off angle was a problem. LCD doens't go big enough for my room (12.5 x 21.5, sitting 12-14 feet from the set), so I guess it's plasma. There are great deals on 50-inch plasmas right now, if I decide that's big enough, but of course it's not 1080p. The salespeople all say we won't see 1080p broadcast for at least 5 years. Is that actually true, or do I put up with all the problems of rear projetion and go that way? Front projection not an option in the room. Thanks. -Dave
