I wouldn't really consider PSO2 an MMO since its only 4 people playing together doing quests from a quest hub. Even worse is comparing it to games like DC Universe which are open world and everyone interacts with one another. Sure PSO has lobbies where large amounts of people get together, but that's the extent of the MMO.
There have been enough MMO's released for consoles to show they have no place on them. The only one that was really successful and available on consoles was Final Fantasy 11, and even it was a pain to play without a keyboard.
A real gamer will buy any system and enjoy it, a tool will sit on a forum trying to bash one or the other!
