It's funny you ask, i asked this same question to a salesman at BestBuy yesterday. He said all HDTV's would look worse on standard Def than regular tube tv's, even the HD tube tv's. He said it will look really grainy. He seemed pretty knowledgeable about all things HD. I did find this a little hard to believe since so many manufacturers say their technology can improve an analog picture. Anyways, unless you plan on using this TV to watch alot of DVD's or play games, you'd be better off waiting. Prices only continue to drop.
