It has been confirmed that a spiritual successor to Conker's Bad Fur Day is in the works here: http://www.screwattack.com/news/news-chris-seavor-conkers-bad-fur-day-making-new-game
And a Banjo Tooie successor is confirmed here: http://www.ign.com/articles/2012/09/27/ex-rare-devs-planning-banjo-tooie-spiritual-successor
Heck yes! We are finally getting what we have been waiting for!!! We are finally getting equivalents to Conker's Other Bad Fur Day and Banjo-Threeie!!!!
Ah, I didn't see that. Nobody was talking about the Bad Fur Day spiritual successor, though. If you ask me, it should be on the 3DS, not just IOS.
