Hi, sorry I've asked before but does the new 6 series Panny give a better pic performance than the 4. I have heard that the 4 was the last display with duel scan, which was omitted from later model's to keep cost's down. So does this affect the quality of the later model's? I have a series 4 & quite happy with it at the moment but with the new digital connection that seem's to be around the corner, those who have had tha chance to compare both plasma's, would it be an improvement to buy a 6 compared to my 4. Thanks.
