Sony will sell the PS4 at a larger loss margin in the US, then in Europe, while losing the least amount in Japan. That is how everyone seems to price their hardware on the world market. The US always gets the best "deal". The PS4 will cost anywhere from 35k to 50k in Japan is my bet. It all depends on what they end up putting under the hood. Either way it is expected that they are spending $100 or more to manufacture it than the Wii U. If they didn't the jump from PS3 would be not be substantial enough. It is not going to be some kind of God machine but you might be surprised what a dedicated system can do with an extra $100 to $200 under the hood. Especially one that launched 1 to 2 years after.
Before the PS3 everyone was nice to me :(
