No clue about the latest Philips panels, sorry. Been out of the entire LCD HDTV buying scene for a while now.
However, I *have* auditioned the Panasonic and Samsung plasmas. Very very close, but the Panasonics have slightly better contrast, ergo deeper blacks, while the Samsung colour reproduction looked better, by a very very small margin.
SD viewing was a wash, DVDs upscaled by the PS3 were excellent on the Panasonic. Samsung was ok, strictly ok. Panel scaling was better on the Panasonic (TH42PV80), however, it doesn't have the 100hz feature of the PX80 sold elsewhere.
I'm waiting to see if someone gets the PZ81 series here, which I will probably purchase. Viewing will be ~25% HD,BR movies and PS3, ~60% SD DVDs upscaled and STB TV, and ~15% PC usage.
Of course, if someone's willing to sponsor a Kuro for me, kindly PM. I will send across my HDFC account number.
