I just got a Wii and am contemplating getting an HDTV to replace my 20" CRT TV. I'm less interested in improved picture quality as I am larger screen size, as I'd go with a 26" or 32" HDTV. However, I've heard that in many cases, the picture quality is actually WORSE on HDTV's as it is on SDTV's? True or not true? I have some component cables on the way for my current TV, which I could use with an HDTV as well.
