PS3 still needs specialized effort compared to X360 based on plenty of developer accounts, though not everyone seems to see it as a big deal. It's not outrageously different, but different enough that it gets plenty of play on the subject of development issues for quite a few studios as evidenced by still recent talk. Any big budget game, I gather, will need more than just the PPU and the RSX to run. UE3 is still an issue on PS3 for some studios, it seems and that is a widely used software base. To say that the PS3 does not have a unique complexity is to call many developers that have expressed that sentiment full of shit. Again, not all developers seem to have the same issues.
