No it really depends on the situation. Delayed games that released on PS3 in regards to Star Ocean: The Last hope, Eternal Sonata, GTA IV: Episodes, Ninja Gaiden Sigma 2(Ninja Gaiden 2) and Bioshock were superior versions of the game. The JRPGs sold better on the PS3 than the 360 counterparts but Bioshock suffered in sales. There are reasons behind timed exclusivity. Microsoft pays towards the game developments through securing timed exclusives which allows the developer to make a superior version of the game for the PS3.
Timed exclusivity in Western themed games would adversely impact on the games sales on the delayed version of the game.
