Since the reported "leak" of a Wii U sequel to DKR surfaced last week and the rumor that Retro provided the Smash 4 team with a new rendition of K. Rool, I was thinking that this may be the big game that Retro has been working on. If all such rumors are true, then maybe K. Rool will be in DKR2.
Remember that Retro helped make Mario Kart 7, if I recall correctly.
That's pretty sweet, I didn't realize anyone was thinking of making another DKR. Retro did a good job making sequels to some other Rare games, though I don't know that any game company can actually surpass Rare. Anyway, I'd probably buy a Wii U just for this if they make it.
