I saw a 530 fresh out of the box Saturday and blurted out "Holy ****" before I even realized it. Without any adjustement it, was by far the best looking HDTV I've seen to date, but I do not proclaim to be the most experienced observer. I have not been able to find the Mits 65711 which I really wanted to compare. They had it hooked up to HD cable on the Discovery channel and it was absolutely breathtaking. DVD's were awesome, too. As for regular cable, maybe looked a little better than what I'm used to. I'm taking the wife back Thurs. for a second look with intentions of buying the 730 if they come in like they are supposed to.
As for Pioneer's lack of info., my dealer said that until Jan. 1, the 720 is the "official" current model and Pio will not recognize the new models until then. He has been a Pio Elite dealer exclusively for 12 years and seems to know what he's talking about as far as I can tell.
