When PS2 classics Ico & Shadow Of The Colossus are re-released on the PS3 next year, they'll look a little nicer. How much nicer? This much nicer.
Now this is reminding me of why I don't own an HDTV. I barely see the difference in clarity.
In fact, the only thing I have ever noticed a major difference in is The Simpsons when I watched its first HD episode online. I guess that's due to my watching it in standard for nearly two decades before.
