Konami is without a doubt Sony's biggest supporter. They've kept most of their big titles on the PS3 and have put only token effort on the other consoles as far as I'm aware of.
This is in contrast to Capcom who is getting pretty far from Sony with all their 360 and Wii support. Square is half way between them where they're still having FF13 on PS3 but all their other big names are starting to move off the PS3 like Last Remnant and FF:CC.
