Nintendo has a model where they will always be profitable. Even the GameCube ended up being quite a profitable entity for them. Microsoft was the least profitable last gen of the three. There's word that they're already making a profit on the 360. I'm not sure I totally buy that, but they're doing better with losses that they were at this time last gen. The PS3 to be profitable is probably going to have to sell 40-60 million world wide. It could be three or four years before Sony is making money on hardware sales. In the end I think Sony will end in the profitable range but it will take a long time.
