Kirby well deserves more reps. It is a fairly well known franchise, and is the fifth highest selling Nintendo game series. It is not any stretch to think that outside of Kirby that others could make it in. If I must be honest, King Dedede deserves to be in more than Wolf, even if I prefer to use Wolf more than any other character. Good thing Dedede is already in.
As far as Chrom, yeah, I am doubting it. I really wish they had gone with him instead of Lucina. Lucina is the only character on the roster that I would cut in a heartbeat.
Anyway, Japan has the most relevance to Sakurai. They come first. I would honestly not be surprised if we got a Kirby rep as a ballot character.
Kirby of course is a well known franchise, but to anyone who is a Nintendo Fan in general but not a Kirby Fan they aren't really going to know anyone besides Kirby, and if they were going to know anyone else it'd be KD and MK who are already in. I don't see Wolf v King Dedede as a thing that makes no sense.
I think the Ballot character will be someone more obscure so that if they don't come back people might miss him but they'd at least understand why they might not have come back and save anyone who actually may have a future of staying in the series for a smash 5 reveal. Snake is gone, and people would like him back because of his unique moveset and he is popular but most people at least recognise that as a 3rd party character he wasn't always guaranteed to come back and the Kojima/Konami thing is a big factor too.
If you look at the various community polls/results you don't see any Kirby rep's in the top 5 at all. You have Wolf and people Like K.Rool.
The DK series has sold way more compared to the Kirby series but DK has less reps then Kirby, which is obviously due to Sakurai Bias which is fair enough can't really blame him for that. 3 seems a good number for somewhat popular nintendo franchises but aren't in the top tier leagues of Zelda, Mario or Pokemon. Anymore then 3 and you start making comparisons and anyone who thinks Kirby is on that level...yeah no.
Of course it wouldn't be so much an issue if he made better use of the current slots aka true clones and DLC wasn't so limited.
[quoteKirby is a pretty big franchise that kinda deserves more reps (bigger than Star Fox). Technically Bandana Dee is a main character now, appearing in multiple Kirby games and was part of the Dream Collection. Bandana Dee is kinda like the Captain Toad of the Kirby franchise in my eyes.[/quote]
Of course its bigger then Star Fox, but the implication there is that warrants cutting SF reps to make room for Kirby reps. It boils down back to the reason Wolf was cut originally. I think it was more in the same boat of Lucas being cut that they planned to bring him back but wanted to focus on new characters first because they always planned to do DLC and SFZ release would be a good time to release Wolf since that would allow more time to work on him.
