I'll be in the market towards the end of this year. For what it's worth, I read the Face-off that Home Theater Magazine did on HD RPTV's in the February issue and the top two sets were the Sony KF-60WE610 (#2 w/ an asterisk) and the Toshiba 65HX93 (#1)
They said that the Sony was probably better if you were looking for a TV to do everything well in bright or dim environments and the Toshiba was the hands down winner for a dedicated HT.
For the entire face-off, you can find it online
HERE .
Good luck with your quest. I'm keeping my ear to the ground to see which will be the one I go with later this year.
As an aside, do TV's come out like cars? (Meaing do they all come out at the same time for that model year) If that's the case, when do the new model year sets come out?
