That's something... I've been reading reviews, comparisons, flames, everything since the PS3 launch in Japan and America, and 98% of the writers expect everything to be better on the PS3 from the word go.
Only 2% or so will actually say that it's going to take devs at least 12 months to start making the most of the PS3, with a couple of years until we see the really amazing games that squeeze every last bit of power from the console.
It amazes me how people can write articles like that without getting their facts right first.
Yes, they couldnt test every game to perfection. Hell, it still plays the majority of PS1-2 games fine. You have to give them credit for having so many work adn they are working on improving it. They want to get them running fully off of emulation. remember, NOTHING is ever perfect.
With respect to the picture being ugly, it has to do with the upscaling of the games. Upscaling a game made for 480i/p to 1080i/p is obviously going to cause it to look bad, I figured that be common sense. Its to much increase, it just blows the image up.
I upscale PS2 games to the native 1600x1200 resolution of my monitor, and it doesn't look close to that bad. Most of the time, I don't even notice the artifacting.
