[Phil Harrison] also confirmed full backwards compatibility to PS1 and PS2 games, full Blu-ray support for games and movies and echoed Ken Kutargi's sentiments on how the HDD is a key component to the system.As I've noted before, I'm skeptical of Sony getting full backward compatibility right. After all, the original PlayStation 2 didn't play some PSOne games correctly. (I should know - I own several of them!) The slim PlayStation 2 model presumably has those problems and it has trouble with a selection of PlayStation 2 games to boot!
Now, on a brand new platform, they're going to get it right? I doubt it. Even Microsoft wasn't so foolhardy as to promise 100% compatibility.
Sure, Sony might come close enough for Average Joe, but (as Ruffin's pointed out) I'm not that guy. I have around 180 PlayStation 2 and PSOne games in my library, and I want to be able to play every one of them. If I have to buy the real hardware, then that's what I'll do, but it'd be nice for Sony to make good on this "full compatibility" promise.
Then there's this:
Regarding backwards compatibility, he said that there might be opportunities for optimization of previous generation games when played on the PS3. However, Sony has no plans for the graphical optimization of downloadable PS1 games on the PSP (which were announced by Ken Kutaragi last week).I'm surprised. Sure, they can't very well improve the polygon models, but pixelization and jaggies will still be visible, even on the smaller PSP screen. Would a little texture smoothing and antialiasing really hurt? And if they're going to be recompiling the games (as I'd suspected they would), some games would benefit from a higher framerate. Perhaps they're just going bare-bones, and if that's the case they better make these games cheap.
They are only promising 100% compatability as long as the game follows the TRC.
Sony can't even manage 100% PS2 compatability on its newer PS2 models.
The whole incompatibility issue just underlines the value of following the manufacturer's guidelines when programming for a console.
