the wii is hardly priced "much above its predecessors". The N64 was $250, the GC was $200. With the Wii + Wii Sports at $250, that is comparable to the previous two consoles, and if we included inflation into the equation, then it is possibly too low.
Sure, it has been 1 year for the Wii, but how many consoles actually had a price cut within the first year? Also, why cut price when you can't possibly produce enough systems. On top of that, I doubt Nintendo will add anything other than a color change for the Wii, and even then that may never happen.
Microsoft on the other hand comes with their windows/office experience where they always have multiple levels of software with different pricing. Since their upper management has been trained that way we can expect similar marketing tactics in the gaming devision. However, since Microsoft is yet to be dominant like the PS1/2 or Wii currently looks to be, I don't really see this as becoming the norm over the course of 10-20 years.
Also, Since Microsoft doesn't see the Wii as competition, I can see, with the PS3 costing $600, why they waited to do a price cut. However, since Sony has gotten close to the XBox360 price, I can see normal price dropping starting to happen.
So no, I don't see this pricing as much more than a 1 generation experiment, where after the Wii dominates the market, and technology becomes cheaper, I expect the next batch of consoles to be in the $250-350 range with better performance than the PS3. With possibly only Microsoft running multiple SKUs
