Is it worth upgrading DVD to progressive scan?

YES - progressive scan is worth it and you are not getting the benefit of the TV without it.
Don't wait, get something now and if you need to, sell it and upgrade later.
You can pickup a Sony 9000ES for around 800 bucks now.

YES!!!

You will be waiting for 2 years then...go ahead with a progressive scan player...

If your set has a really good line doubler then there is only a slight difference going to progressive. I'd say the image is more film-like. I use the Panasonic RP91 with progressive feeding my Pioneer Elite. The Pioneer has a very good doubler so the difference is slight but it is better using the DVD player in progressive mode. It's close though. Hope this helps.

I could see a noticeable difference between my sony 7700/xbr200 and my friend's sony 9000/xbr400. The images seemed more solid and three dimensional. Not enough for me to upgrade though. The 7700 has a HUGE advantage over the 9000 in that it plays all of the vcd (video cd) formats.

My computer w/ Sony gdm-fw900 24" flat crt beats both of these.
