Completely agree with SmokedHostage.
Nintendo is making a console not because people want it, but because it's developpers want a new toy to play with, not giving a damn about anything else apparently, and to appease for some reason 3rd parties, which have brainwashed Nintendo into thinking that their mediocre games aren't selling because of them.
Their obsession with 3D ( I mean, the 3DS essentially revovles around this, and only this ), and making artsy games and ruining game series is going to backfire on them completely next generation.
Also, saying that the 3DS is selling OK because it's making Nintendo money is missing the point entirely, like praising a game just because it's playable. The problem will be why it will be selling so much less than the DS, which happens to be bad for them.
Oh yeah, and for those who say we can't know anything right now about their next console, or how successful it can be, just like how the DS's and Wii's success were "unpredictable", you're wrong, if you look at the wrong things, your conclusions will also be wrong, but if you look at the right things, their success's and Nntendo's future are nearly as clear as day.
