It's been a while since I've taken a look, but I found it on a link on one of the forums I was on, and then went, read it, then moved on. I think it may have come from AVS, but I'm not positive.
Reviewing that article, it definitely was something that was done after it was written and included actual screen shots comparing specific upconverted frames and scaling quality as handled by multiple players, including the A2, Oppo, and PS3. It was interesting to read, but I'm not sure how 'official' it was.
The bottom line really is that both the A2, XA2, and PS3, and other HD players do have the guts to do great upconversion as well as the capability of delivering HD video.
For those with a universal remote, Nyko has an IR remote (USB/IR) that works with the PS3. It can't control power, but controls all other functionality and works pretty well. I've got it tied into my system and my wife has no issues with it at all.
