Ignore the fact that you'd have to get Sony, Nintendo and MS to cooperate with their matchmaking systems and such first.
Hi! Welcome to 2009! You may notice a new technology named ARPANET, colloquially known as "the Internet." The Internet allows you to communicate across vast distances at high speeds, and was designed with a set of protocols to facilitate these communications. These protocols are platform and computer architecture independent, and as such, said protocols may facilitate communication between two very different systems.
Seriously though, the only reason is to sell PS3 hardware, since their standard means have not led to great success on this generation of the Playstation. I point you to the case of Quake3 on the Dreamcast being fully compatible with all other ports of Quake3 as proof that Sony is just trying to sap your wallet of $300+ to play the same fucking game and alienate all of your Xbox owning friends.
