GBA Successor Revisit

Do you remember this article? Back on March 1, CNN speculated that the GBA successor would be shown this year. Well it turned out to be a new model in the form of the Micro rather than the speculated successor. So what about a true successor? How soon might we know more about it?

Which leads me to ask, what should Ninny do with the next installment of the GameBoy? Would a portable GameCube with four buttons keep you happy, or are you looking for a Revolution/DS effect?
