Well one thing we need to keep in mind that "historical value" isn't the sole reason we had
. In addition to that, they were also included as "surprise characters", who would be unexpected newcomers absolutely no one could guess. While some characters, like Bowser Jr., Robin, Shulk, Villager, etc. could be feasibly predicted, there was nothing to suggest that these three would be playable (ignoring the
Duck Hunt ducks trophy in
Melee). This gives them the "surprise character" trait, as they are meant to surprise players when they are unlocked (or leaked). With this in mind, a character like this is pretty difficult to predict. I suppose that's the point
If I did have to wager a guess, and assuming we don't get another fighter to represent the fighting style I'd place my bets on Fighter Hayabusa or Star Man from
Pro Wrestling. It's a pretty iconic NES game with a lot of historical value, and the concept of a wrestling playstyle opens up for interesting concepts. Plus, above all else, they haven't done anything in previous
Smash games to lead fans to predicting their inclusion. The perfect "surprise character" if you ask me.
By no means am I saying they're a "shoe-in", as there are probably plenty of other characters that fit the criteria (Ossan from
Golf comes to mind considering he has the legacy of the late Iwata at his side), those are just my thoughts.
