If I understand the scaling issue correctly, the PS3 does not scale games at all.
In that case, when you select 480p ... the PS3 isn't downresing the game to that resolution ... the game is simply internally rendered at 480p.
If that is the case, there goes the free AA (basically automatic supersampling) for SD TV's.
That gives 360 a huge IQ advantage on SD TV's.
Certainly the devs can turn on some massive AA when rendering at 480p, and that will get rid of jaggies ... but it won't improve detail.
A way around this is to render the game at 720p, and then downsample to 480p. A dev would have to answer this ... but I'm guessing that wouldn't have much in the way overhead. The problem however, is that it isn't automated ... it is left to the dev to implement this.
I expect many devs will in the future, but a lot of first gen games won't ... and those are the games more people will be playing on SD TV's over the next year or two.
