As far as I can tell, this is a bunch of crap (though, what do you expect from a Best Buy salesman?). No networks are currently broadcasting in 1080p, or plan to do so any time in the near future. There are some HD-DVD and Blu-Ray discs encoded at 1080p, but that's about it. As others have said, and based on everything I've heard, its pretty difficult to tell the difference on a TV under 50" unless you sit a couple feet away. If the price difference isn't that much, I don't see any problem with getting a 1080p TV, but its probably not necessary at this point.
