A bit of a dilemna here... I'm thinking of buying the Pioneer PDP-504HDE, which will be discontinued soon to make way for the upcoming PDP-505XDE. I can get it for quite a cheap price at my local store. Does anyone know anything about the newer 505XDE models? Is it worth holding back on the 504HDE, and paying whatever extra for the 505XDE? Does anyone know how much of an improvement is the newer model? They say the 505XDE has 7 billion colours, on paper it sounds nice, but I don't know how significant this improvement will be in reality. Also, the digital freeview that comes built into the 505XDE isn't an importance to me, as I already have a Sky receiver. Apart from the 7 billion colours, the built in digital receiver and plastic front (to reduce reflection), there are no other big differences betweent he two models. If the improvement in the new model isn't so significant, then it may be worthless for me to pay a lot extra for this slight difference, and I may as well buy the current model while it's going cheap. Unfortunately, there are no reviews yet in the magazines, so if I wait for the new sets to be reviewed or displayed in the shops and find there's no vast improvement, then it would be too late for me to get the (cheaper) older model as it'll all be sold out. Thanks.
