@Rolstoppable you think that any company will be mad if they "only" sell more than million copys on 1 platform??? I wonder what system you were playing last gen. You strike me as a person who just jumped on the bandwagon 3 years ago. As for fighting games, MS & Sony dont look like their going anywhere, so we'll never find out.
You keep missing the point. The question is can Sony's first party alone keep a platform going. Obviously that's not the case when you look at how much their games sell. One million or two or three just aren't enough to argue that Sony's first party is capable of carrying an entire platform on its own. Hence why it makes sense to say that Move needs good third party support as well in order to succeed. There's only one big Sony franchise and that's Gran Turismo.
As for fighting games: even if a scenario is unlikely to happen (like both Sony & Microsoft leaving the console business), you can still work with probabilities to imagine what the most likely outcome is going to be. I think my argument has been pretty solid and all you have done is trying to deflect the point in order to not have to say that you were wrong.
