My big question for the new Sony BD players, are they still using a hardware chipset that has inaccurate video decoding to HDMI output levels. This was an issue with all of the x70 and x80 series (and probably earlier series also) of Sony BD players. The on-line web site "Secrets of Home Theater and High Fidelity" first reported on this issue with the Sony chipset last year (HERE is Part I of the article and HERE is Part II - also see subsquent BD player reviews that report on this issue). One consequence of this issue is if you have calibrated your HDTV for other sources connected via HDMI then the gamma curve will be non-linear and different when the Sony BD player is used as the source. The PS3 does not appears to have this issue (it does the decoding in software rather than the dedicated hardware that is used in the Sony standalone BD players). Some other brands of BD players either do not have this issue (e.g., Oppo) or only have a similar issue when certain video processing options are turned on by the user (e.g., Panasonic).
