From Kotaku:
Sony is apparently pitching features like these to developers to extend the lives of their titles, using strong first and second party development showcases to prove that Home can effectively market outside of traditional means. We hope they take them up on their offer, because we’re definitely excited about the prospects.
Kotaku has examples of extra Home integration with Warhawk, Resistance: Fall of Man and Uncharted: Drake’s Fortune. If developers add this extra functionality into their titles then the PS3 could leap ahead of the Xbox 360 for sheer richness in online offerings. As of yet, the Xbox 360 is quite far ahead.
