Here's my wish list for the next DKC:
- Ability to play as DK and modify his powers with a buddy, like normal, OR switch to your partner character, at which point DK disappears but you still have four hearts, and you can change back to DK (with buddy in tow) at any time. So you can play as Diddy by himself (like in TF's Hard Mode), but at any time you can tag-team back to DK (with Diddy in tow).
- Bring back Kaptain K. Rool and the Pirate Kremlings, with Crocodile Isle rising from the depths. Go all-out with a remake/reimagining of the worlds in DKC2, with a new world here and there, but the same dark atmosphere. Similar to what Returns did with DKC1, remaking most of its worlds, with the occasional artistic license (I.E. the all-new Cliffs world). If Returns was a spiritual successor to DCK1, and if Tropical Freeze is (arguably) a spiritual successor to DKC3 (with the woodsy "wonders of nature" feel), then the grand finale of the Retro DKC trilogy should be the spiritual successor to DKC2.
