Let's go back to discussing Chibi Robo.
This game might have bombed, but it certainly made the character into a very specific, even unique, fighter; in addition to Sakurai being a fan of the character, I believe he may get in to save his franchise (because by now, Nintendo is starting to slowly wise up to this fact, and other facts about how to leverage their IPs to make money).
I think he is one of the most likely characters.
Peek a boo, chibi sees you, smash ball.
Great, people overrating Shovel Knight in terms of his significance to Nintendo. If any third-party franchise is getting heavily pushed by Nintendo, it's obviously Yo-Kai Watch and yet I don't see tons of people saying Jibanyan is likely because of that despite Yo-Kai Watch being a much bigger franchise over in Japan than Shovel Knight is anywhere. Shove Knight getting an amiibo (one that Yacht Club Games themselves produced and Nintendo merely licensed) no longer means anything considering it's confirmed that any indie character can have an amiibo made for them.
As for Inklings, they don't need a rumour to support them either way as they have plenty of merits to make it in as Smash DLC. They are easily one of the most highly requested characters in general and probably the most highly requested newcomer franchise character in the West (the only newcomer Nintendo franchise character that rivals their demands in the West is Isaac). Over in Japan, they still maintain their high level of requests. They also have great uniqueness potential due to their ink mechanics. Also, Splatoon was such a huge success.
I will come forth and say, the biggest point in Shovel Knight's favor (from my perspective, of course) is how much

is adamant about the character being added. He seems to be snooping somewhere he cannot report upon, and I trust him quite much in regard to where his nose leads him.
@GreenKirby
Shovel Knight is the epitome of confirmation bias. Quite literally, everywhere I've even attempted to bring up a conversation on the matter, it nearly dissolves into that very fact, minus the phrase.
The last conversation I tried to open was on this very board, and it ended up convincing me even further that his only merit, as having appeared in many games in his one year of life, has more to do with the Yacht Club being a wealthy company who can afford to push him and make him an amiibo (and ironically, name their company so imperials, to boot!); as I said above, the only factoid that makes me believe in him is the opinion of another user.
