Stacey is amazing. Here are his last objective measurements. I await his and Kris's assesments of the A2/XA2.

PS3 Objective Measurements
I ran some objective tests on the PS3 today, my results are below. I have included Panasonic, Samsung and Toshiba results as well. I only looked at the HDMI to HDMI scenario.
I fed the output of the PS3 (and other players) into a DVDO VP50 and then into the Marantz VP11S1. I looked at both the 1080p and 1080i outputs.
HDMI Output Format
PS3
R'G'B'
Panasonic DMP-BD10
Y'CbCr 4:4:4
Toshiba HD-A1
Y'CbCr 4:2:2
Samsung BD-P1000
Y'CbCr 4:4:4
Pixel Cropping:
PS3
Left: 0
Top: 0
Right: 0
Bottom: 0
Comments: This is perfect behavior. You actually get all 1920x1080 pixels.
Panasonic DMP-BD10

Toshiba HD-A1

Comments: This is perfect behavior. You actually get all 1920x1080 pixels.
Samsung BD-P1000
Left: 8
Top: 2
Right: 1
Bottom: 0
Comments: As you can tell,
the Samsung is not able to provide a true 1920x1080 active image. You are only getting 1911x1078 of real picture.
Dynamic Range - HDMI to HDMI
PS3
Above White - Fail - Clips
Below Black - Fail - Clips
Panasonic DMP-BD10
Above White - Fail - Clips
Below Black - Fail - Clips
Comments: The player has built-in picture controls. If you lower contrast down to -4 through -7, it will no longer clip. However, you are compressing the dynamic range. Steps are introduced, which show up as contouring. If you adjust brightness, you can make below black appear. If you do this, you are actually raising the black level of the player. I suspect this clipping may be caused by the bug in the Silicon Image 9030 HDMI transmitter. If they were to output Y'CbCr 4:2:2, it may fix the problem. I recommend you do not change the picture controls.
Toshiba HD-A1
Above White - Pass
Below Black - Pass
Samsung BD-P1000
Above White - Pass
Below Black - Pass
Luma Resolution
I looked at both horizontal and vertical resolution out to Nyquist. All four players were fine in this regard. There was no apparent roll-off.
Chroma Resolution
PS3
The horizontal Nyquist burst was rolled-off. It was not gone like the BD-10, but not as good as the Samsung and Toshiba.
Panasonic DMP-BD10
The horizontal Nyquist burst was pretty much gray. Something in the player must be filtering out this high resolution information. Vertical was fine.
Toshiba HD-A1
Both horizontal and vertical produced the full resolution out to Nyquist.
Samsung BD-P1000
There was a loss of vertical resolution at Nyquist. I suspect this is caused by the filtering in the Cortez (Genesis/Faroudja) chip.
Chroma Bug
PS3
ICP: This player does not have a filter to reduce the ICP artifact.
2-2: Pass - This player does not suffer from 2-2 chroma bug.
2-3: Pass - This player does not suffer from 2-3 chroma bug.
Comments: The upsampling it not high quality, though it is correct. You can see some steps in the chroma. The BD-10 looked better, when it did not have CUE.
Panasonic DMP-BD10
ICP: This player does not have a filter to reduce the ICP artifact.
2-2: Pass - This player does not suffer from 2-2 chroma bug.
2-3: Pass - This player does not suffer from 2-3 chroma bug.
*1.02 FW update - I am not sure what happened, but it now has CUE. I am going to try and locate a 1.0 player just to double check my original results.
2-2: Fail - This player suffers from 2-2 chroma bug.
2-3: Fail - This player suffers from 2-3 chroma bug.
Toshiba HD-A1
ICP: This player does not have a filter to reduce the ICP artifact.
2-2: Fail - This player suffers from the 2-2 chroma bug.
2-3: Fail - This player suffers from the 2-3 chroma bug.
Samsung BD-P1000
ICP: This player does include a filter to reduce the ICP artifact. Sadly it is present on both 1080i and 1080p. If a filter is included, it should only exist for the 1080p output.
2-2: Fail - This player suffers from the 2-2 chroma bug.
2-3: Fail - This player suffers from the 2-3 chroma bug.
Deinterlacing
The PS3 does not appear to be able to output 1080p when the source is encoded as 1080i. It changes the output resolution back to 1080i while 1080i content is playing. The Panasonic is using the AVC2510 while the Samsung is using the Cortez. Neither player can deinterlace 2-2, but both support 2-3 deinterlacing.
If you have the DVDO VP50, Anthem D2 or the Marantz VP11S1, I highly recommend you use the 1080i output of these players. It will do a better job creating the 1080p image than the players will. "
I have bolded where units failed. As you can see the A1 fails the ICP test and exhibits CUE (unbeknowest to me). Otherwise it beats or meets his rigorous tests.
