A price cut would be a bad business move at this point. The people are still buying it in droves. Wait and drop the price when the sales slow and you can earn more money. Your early adopters will not feel cheated and you will make more profit that can go back into the business.
As for a successor, they are probably witholding info, but lets have fun.
To my tech friends, could Nintendo not release an ehanced dock that would enhance the console further in about a year and then release a new tablet that is stronger in every way? Then just rotate those two things from now until x amount of generations from now? (I doubt the dock could enhance it that much) I mean this could be a great way to release further Generations that are competitive for a much smaller price.
