I think the PS3 has several advantages:
- all systems have hard-drives - this means that game developers can count on using the HDD - only some 360 models have HDDs and thus those developers have to design for the lowest common denominator.
- Reliability is second to none - the 360 has had serious reliability issues which you mentioned. I have a launch PS3 and it's never skipped a beat, and it's never skipped playing a DVD/Blu-Ray either.
- Blu-Ray, two reasons, first is movie playback which is flawless on DVD and Blu-Rays, second is games. Again developers know they have 10G to work with in designing a game (and the HDD for performance) - will they use it all.... MGS4 did! Game size will follow the hardware and sooner or later the game developers will design toward the expanded capacity of Blu Ray.
- Bluetooth works great for remotes, controllers.....
