Even though there was some bs talk by Retro about how they weren't done with the franchise because of water segments or dynamic camera (which barely showed up in stages), or whatever, the reality is probably that Nintendo saw DKCR outselling all other Retro titles combined, so they really had no choice other than making a second one, especially since most early WiiU titles are just repeats of the Wii's ,,biggest hits''.
Now that TF bombed into oblivion, the IP must have lost any kind of priority for them, so I don't see it coming back that soon, unless one of the parties involved really demands it (but why would they? Unless they come up with a completely new concept).
And considering that WiiU is ,,boxed cancer'', I wouldn't be surprised if there isn't another WiiU Retro title at all. What they have in the pipeline right now is mostly enough for a dead platform and they can treat lots of stuff from last year like new announcments (like Starfox). And it's not like they care about preventing droughts anymore.
