There is little doubt in my mind that the Wii will be the most profitable of the 3 systems this generation, both in terms of console profits and software. But if we are looking near future, we have the Zapper and Wiiboard on the horizon. And I believe Nintendo has created a patent or trademark for a body controller. Though what this is, is anyone's guess. Also Nintendo has a wealth of unexplored franchises that will take them past 2010. Icarus, Pilotwings, Starfox, FZero. And of course there are new innovative games that make use of the Wiimote. Nintendo is probable the least worried of the 3 companies right now. Though from interviews from Iwata, they will continue to challenge themselves. I think a better question would be, how will Sony and Microsoft challenge themselves next?
