Is it critical that I get a 1080p HDTV? I am currenty researching TV's and Ive heard that this is the wave of the future. I need a 60" hdtv for the new house which will be finished the end of July. Should I spring for the extra bucks for a sep 1080p input(ala Sony XBR) or is still ok to go with a 720? How much of a difference is there between them?Thank you for all your respones. By the way my budget is $2500--any suggestions for a 60 HDTV??
