well, we can wait then.I think people actually need to see the game before we predict 3m sales.
And lets be honest. Nintendo would be better off not naking Metroid ever if they were concerned about sales.
as for the second statement, I think that's true but to a certain extent.. It doesn't have to be super successful, but I think the entries have to do a certain amount, or else it'd be dead. So I'd say they're somewhat invested in its sales
