Quite possibly one of those "purple monkey dishwasher" instances, supposedly Sir Miyamoto commented to a journalist of the French variety that a new title would be debuted for the DS at the company's E3 press conference. This mystery title, if the post linked is to be believed, will be very similar to once-hot, now-not franchise Starfox.
Everyone is already going wild on the internet speculating that it is none other than the infamous Starfox 2, a game that was supposedly in finished beta form, yet never released due to the age of the hardware. Sir Shig's comment, which is supposedly this, when translated mentions nothing about this, so believe what you will.
