I, and expect some others, purchased this along with a Samsung 3d tv, mainly because the 3d Kit (two pairs of 3d glasses and Blu-ray 3d "Monsters vs Aliens") was included for free.

Seems to work pretty well, and have lots of apps for streaming from various sources such as Blockbusters and Vudu, plus other apps. One clear negative, only one HDMI output but does include 7.1 analog output. I am using this to connect to my Denon 5800 which doesn't have HDMI anyway. They have announced a BD-C7900 for $50 more (MSRP) that has two HDMI but no 7.1 analog outputs. I believe both Panasonic 3d players have 2 HDMI outputs and 7.1 analog outputs.
With what they call BD-Wise, the player tends to send the video output out in the native video of the disc and lets the TV do any progressive conversion and 1080p upscaling. But you can set the player to do this if you wish. Either way the picture quality seens excellent. I don't have much to compare it to. I Currently use PS3's to my other HD sets but didn't try switching around for a comparison between them.
