According to IGN, Retro Studios is currently working on a sequel to Donkey Kong. IGN did not cite the source of the rumors, but Retro Studios said, in a talk with IGN, that "they think you'll be very excited when you find out what they're working on."

"The rumors start flying around this time, just days before Nintendo pops the lid off its hugely secretive line-up at its E3 press conference. One of the wildest, but certainly credible, rumors we've just heard in the halls from those in the know: Retro Studios is now working its magic on a Wii game starring Donkey Kong." - from IGN
