***Just got my New WD-65738 today =) I had a 62725 that had a bad chassis last year and then this year a bad light engine. Worked with Mitsubishi on a DEAL for the 65738.
FIrst impression...NICE!!! Alittle bright out-of-the-box, but I plan to run the AVIA disc to set it up. Even thought it's a 65", it actually looks smaller than my 62725 due to the lack of a frame around the screen.
Day 1 Impressions:
Picture is great. 1080p at 120Hz, Nice Black level,
3 HDMI ports plus 2 composite.
No Netcommand

I actually kinda miss it.
StreamTV (Vudu) is kinda neat. Althought it keeps losing my facebook and twitter credentials and the weather app bombs out.
New menu system is nice and fluid.
When using with Comcast STB, the delay when switching formats is alittle long. Even when going to DVR or On Demmand.
Matching base has lots of room for all my components, including my power conditioner =)
Trying to figure it all out, but so far, I'm impressed.
WHen my light engine went on my 62725 (Out of warranty of course), the service tech told me that Mitsubishi is one of ther better companies to negotiate with. He was right. THey came through for me big time...THANKS MITSUBISHI.
