But that's the exact opposite of what happens.
The "big money" comes from endless amounts of useless downloadable content, pre-orders and millions spent on marketing. In the long-term, PC versions of games will generate the most revenue for the fact that they are always there, always available. And MMO games are as long-term as it gets, that's why most of them stay PC exclusives. Consoles will have different generations with no backwards compatibility and the bulk of their user base will jump on the next game that had better advertising than the one they played before.
