Of-course.
But bear in mind that the world economy will probably be in greater dire straits than it is now, the collapse of the Euro rests on a knife-edge and we also face the prospect of a credit crunch 2.0.
If we can accept that $200 is the mass market price point, Nintendo should be thinking of an initial price point that will let them achieve that figure in as quick a time as possible or for when further competition arrives (PS4, 720 etc).
Nintendo just cannot afford another 3DS type price point fiasco. Personally, I think Nintendo will be doing everything in their power to launch at the $250 price point with an introductory Wii Sports type game included. This will probably mean that, like Gamecube, they'll be taking a small inital loss for perhaps the first six months or so as production and economies of scale ramp up.
