Dunne also revealed the game eventually released as Banjo Pilot on Game Boy Advance was originally going to be Donkey Kong Pilot and was actually completed. But once Rare was sold to Microsoft, they couldn't use the Donkey Kong license and that become Banjo.
That's no revelation to me, I still have an old magazine at home from back in the days showing screenshots of the DK branded version of the game. If I recall correctly, it was supposed to be "Diddy Kong Pilot", not "Donkey Kong Pilot".
