Some devs have spoken about this, like the Burnout Paradise devs spoke about this as a relative PS3 advantage over the 360. The data duplication tactic you comment on was exaggerated though and dragged out of context, Bethesda used the same methods for the 360 version. Of course the Blu-Ray drive is slower than a harddrive, but not really worse than the 360 DVD drive in any regard.
"Bethesda's Pete Hines also commented that recent reports f data duplication on the PS3 Oblivion disc have been exaggerated, and his technique isn't different than the similar strategy that was mployed in the creation of the Xbox 360 game last year. "
No, they are seperate. One dev words it like this: "because it's not as strongly defined, you have the freedom to do it in the way that you want [on PSN] - in a way that may be more suitable to your game."
Think about it like this, if you want to implement online multiplayer you have to follow strict Microsoft protocols. This is easier with regard to developement (devs don't need to think about what approach best suits their game), but also less powerful if the devs think up their own methods how to implement such stuff.
