If (only if) K.Rool doesn't make in Smash4, probably we're still getting some Kremling (and K.Rool) related Trophy as we had in Brawl.. it's like... impossible, make a Trophy Gallery of Donkey Kong story without mention the reptiles..So, even if Nintendo want somehow that the Kremlings stay in the limbo, they can't... but aside this fact, I think that Nintendo has plans to the Kremlings.. holding them for a next game, for hype, I dunno.. a friend of mine had a theory about Retro's DKC, saying that first we got something related to indigenous culture, now, something between Ice Age and Vikings... I don't know where exactly he wanted to reach, but he said that the Kremlings could be the next crew to attack DK's Island, for relate to human evolution/story, something like that. '-'
