I think it has something to do with the gaming features the N5 supposed to have. What if they were to put a touch screen on the N5 or better yet the DS touch screen can be used through a wireless connection.
Iwata has already hinted that the N5 would offer much more than mere gameplay functionality, so this speculation is as good as any. However, the DS/Nitro is not the true successor to the GBA SP, this is supposedly the 3rd pillar. Also that in the interim they would be developing a true GBA
successor.
