Early in this gen many games were originally being developed for PC and 360, then being ported over to the PS3 and with this, it was often said that xbox 360 versions of games were vastly superior to the PS3 versions of those games.
However, as Now Gaming website reports:
http://www.nowgamer.com/features/682/developers-shift-to-leading-on-ps3?o=2#listing ,
many high profile developers including Yoshinori Kitase of Square (saying he prefers to use the PS3 as his lead development platform because he can push graphics much further with the PS3), Crytek (making the PS3 their lead platform for Crysis 2's console development), and even Bioware are now opting to use the PS3 as their lead platform in the design of their console games.
Reasons given for this shift include the graphical abilitities of the PS3, development on PS3 giving developers a great practice run in programming for the next generation of pc games since it is speculated that future computer multi-core processors will be similar to the current architecture of the PS3; and the fact that it is early in the PS3's lifespan and developers are very curious to see just how far they can push the PS3 architecture.
So, it appears that as far as the development of console games is concerned and for the PS3 as a second or even third choice in the development of console games the times are changing.
