Theory: Barely anything has been seen from the DK series because it still has at least one character left to be revealed.
Nothing ground-breaking, right? And it's not exclusive to DK because we haven't seen anything from similarly-sized (as far as Smash goes, not in reality) series Kirby and Star Fox, right?
Kirby and Star Fox still have characters left to be revealed as well in Meta Knight, Falco, and Wolf. DK, however, has both its veterans revealed, but is still receiving this treatment. Coincidence? I think not.
Not really intended as a waterproof theory, but just food for thought.
