I wonder how much of a loss they're taking at launch. Three years to make a profit seems... unwise. That seems like a fairly long time, and you never know what may happen that will delay any potential profits. I'm surprised they're willing to lose money on it for so long after what happened with the PS3.
And just to clarify, does anyone know if Sony is only talking about the hardware? Or are they including all the games and accessories in their estimate when talking about making a profit? I assume it's the former, but I'm not sure.
