First up: an assumption. Console owners want to play massively multiplayer games. This is far from unreasonable; there was a time when no console gamer would be seen dead playing a first-person shooter (except, of course, for GoldenEye). Now you can't move for high-budget, high-adrenaline FPS console hits. Looking at the huge success of World of Warcraft, it's clear the MMO genre has just as much growing room.
