I think when people are starved for information, they start to overthink some things and start to worry about things.
Enter Geno's chances. I said this Sunday, but looking at the objective facts, Geno's chances are pretty darn great. I mean sure, you could subscribe to the mentality wynn has, but I think Sakurai including Banjo & Kazooie shatters any rule or any doubt you could have really (yes, that's an oversimplification somewhat, but I've already typed out a bunch regarding this subject before).
Also, I think ForsakenM's message to Sereneda was spot on. I think it is important to remember Geno's place in the grander scheme of things. Not to demean Geno (as I've prefaced by saying this before), but he IS super irrelevant and pretty niche. The great thing about Smash and Sakurai though is that he has created a roster that can facilitate such a discussion of older and/or more niche characters (like King K. Rool, Banjo & Kazooie, Isaac, etc.). I mean the fact that Geno (a character who has been in literally nothing for many many years) got a Mii costume is worth celebrating I feel (again, I'm NOT trying to belittle Geno, I'm just saying the facts and putting things into perspective). Truly, it really is a balance between fan picks and those legacy characters. I know some people think it should ALWAYS be top fan picks, but I don't think that is wise because it has been proven how much the Smash community can have tunnel vision and overlook a character's impact and cultural relevance (see Hero, Terry, etc.). As I've said before, Smash is Sakurai's baby. While it has been proven he cares about pleasing us, Smash is HIS vision. As such, Sakurai should have the freedom to add a character he wants without the Smash community badgering him (see Piranha Plant, Joker, etc.).
I want Geno in due to you guys, not due to personal attachment. But yeah, ForsakenM said it best with that Star Wars analogy: if you could choose Luke Skywalker and Darth Vader, why would you choose Boba Fett? Sure, Boba Fett is popular and has a sizable fan support, but he is also a smaller character who hasn't had the huge cultural impact Luke and Vader have had (aka, Cloud & Hero vs. Geno). I do like Serenade, but people who have the reaction like he has been having are kind of ridiculous. Again, who cares that Geno wasn't originally planned? We don't live in the timeline where there was no more DLC. Thankfully, there IS more DLC. So, why worry about what wasn't rather than look forward?
