Luckily then that they are so similar in performance. |
Overall the PS3 has memory advantages as it has a default harddrive for caching data (compare with virtual memory on a PC) and better bandwidth.
The 360 Arcade model is most problematic for designing current multi-platform high definition games. The Cell can handle everything the Xenon does (although the code has to be properly designed, refer to earlier quotes as examples).
Deferred rendering would be possible on the 360, but it's far too weak for that. Some GPU techniques on the 360 are incompatible with the doing this on PS3 directly like it is done on the 360, however indirectly everything can be implemented through the Cell (that means having game engines which are partly pretty different on both platforms).
There are other considerations such as a multi-platform game cannot rely on motion controls. Specs wise the PS3 is far more powerful, but the 360 is powerful enough for decent multi-platform high definition games.
Regarding 2008:

"And the winner is.... "Playstation 3"!
The tides have truly turned in 2008. Developers finally up to speed with the Playstation hardware, so multi-platform games are on equal footing.
Then you have to look at the exclusives for each platform. When stacking up the PS3 holding releases against those of the 360, there's really no contest in quality and quantity"
Regarding 2009, the gap between PS3 and 360 exclusives will widen. IMO this process is going to continue for years and later PS3 games will not look like as if these games were designed for the same platform as PS3 launch games.
