I think Sony will be happy with 50 million LT (or 60-75 million as TheSource predicted) for PS3 and ends at 3rd place if they are profitable with it. The problem is they are not.
During the N64 and NGC eras, Nintendo sold a little over 50 million combined for two generations but still made money then. Now they are just making insane amount of money. Since they have been through the "bad" time then, the worst that can happen to Nintendo next gen is they ended up losing the console wars again. However, they would still make money. It just won't be insane amount of money.
MikeB predicts that the PS3 will sell about 140 million units by the end of 2016 and triple the amount of 360s in the long run.
