Ninja Gaiden 2 not so HD 585p

The point is, upsampling kills the crispness and precision of the images and ninja gaiden's visuals suffer because of it - the interpolating required to fill up the extra lines hurts the visual presentation of the game.

I don't get it: Either you state for the hundredth time something totally banal :native 720p images look better than upscaled 720p images from a native 640p source. I can assure you nobody is disputing that and if you should be a Captain Obvious who argues for this statement for half a thread I would advise you to make more precise statements.
OR
you say that upscaling makes an image worse than a native 640p image of the same size. (for example on a TV with lower resolution or in native resolution nearer to the TV) And this just isn't correct (at least not in a meaningful way). Any display of a digital image does a scaling in some way after all. Good upscaling doesn't add but it also doesn't reduce details.

test groups have shown people do notice a difference between CD audio and the "high res" sound formats

I believe it when I see it. The SNR of any normal sound system is so much worse that I really doubt that this has been consistently shown with good studies and large usergroups. Sounds more like an audiophil dream. Tests by big computer magazins have shown that people do not even hear a difference between 256 mbit mp3s and CD.

 It's true that there's a lot of superstition involved in the whole audiophile business, but those test group reports were enough to make manufacturers invest millions in launching improved audio formats. It does require well crafted gear and even proper room acoustics (which was ultimately the demise of the whole endeavour), but the difference is there. I personally can notice the difference you mention - usually my pmp is loaded with 256mbit mp3s but the other day I picked up some tracks I had stored in PCM and oh god, I almost forgot how good a CD sounds compared with mp3 or ATRAC tracks. 

Finally, about the interpolation dispute, I'm glad you are on board.
