depends man the 700 will basically be the px70 with better speakers, extra HDMI, anti reflection coating and SD card slot.
Personally the only appeal for me was the anto-glare but have read reports it CAN have slight adverse effect to picture so didnt bother waiting.
If you play a lot of games you get the odd green fringe from high contrast games like Gears Of War - see www.* for explanation and review.
The HD picture on the px70 is absolutely stunning, and has very inky blacks. The performance is fantastic. SD freeview is very good too, especially with a good signal. Some people have complained picture is a bit 'soft' - so I think it comes down to signal etc
DVD performance (SD) is very very good, I have just bought VGA cable for xbox360, and picture is stunning, no bleeding, natural colours and upscaled very nicely. It has convinced me to but an Oppo 981 upscale player, or new Panny DVD HDD / Freeview recorde which upscales. Not decided yet.
The Pioneer 427XD is a sterling Plasma - the SD picture it has to be said is amazing. As is the HD performance. There is no real noticeable diff between Pio and Panny on DVD and HD, I think the Panny edges it on blacks, and the Pio has better greens. My mate has PS3 we watched Casino Royale on blueray, it looked great - to be honest I couldnt see much diff when i went home and played my SD version through the 360. I guess if you did side by side you might see a diff, but was not that amazing that made me want to run and buy a PS3. In fact I was until I saw it, now I am content to upscale my current collection until prices drop, and more titles are out - then i can replace ad hoc!
Downfalls on Pio? Not many - dirty screen issue some people have, and the price - the Pio is about £1250 WITHOUT a stand, so really comes in aboput £400 more than the Panny. Therefore for me was a no brainer as I can see no great reason why the Pio is worth an extra load of my cash having seen my mates run for months.
I now have extra cash for more kit!!!! (The oppo or Panny set)
He has seen my Panny a few times now and concedes it is on par with the Pio.
Both handle sports very nicely, both look nice, well i think so i love the black look. it 'blends' in to surroundings well.
The panny is not noisy, it has no fans, and the picture just gets better with each week.
Oh one other point I would say the Panny is FAR easier to calibrate, it took my mate hours and hours to calibrate the Pio, it has hundreds of little settings if you like that sort of stuff.
The panny needs very very little calibrating - switch to cinema, knock down brightness a bit, switch colour to warm and you are pretty much there!
Hope this helps
