To throw in my opinions on the Porky stuff that’s been brought up recently...
Porky is the most recognizable villain from his series next to Giygas, and even then the two can easily be switched around. (Speaking of, why do neither of the two biggest villains of the series have anything to represent them???)
If they wanted to include Porky as a boss, but scrapped him, I see no reason why the Spirit that likely would’ve come with him couldn’t at least be summonable. However, I can still see him returning as a boss in a future update, though I don’t know how likely it is they’d throw in more bosses since we already have the nice round number of 10.
As for Mother 3 not being officially released in the West, nearly everyone that wants to play the game has already done so via the fan translation. Nintendo has even acknowledged the demand for the game at that one Robot Chicken E3 stunt. And yes, apart from that, they haven’t really done anything about it, but I highly doubt they don’t recognize the demand and don’t recognize how many people have already had experience with the game.
There’s also the comment that “all his supporters back the Spirits Deconfirm theory”. To offer a different perspective from CJBrine, I do follow with this theory. But I also think that, as a whole, the entire Smash community is split on this issue. In other words, I don’t think it’s a stretch to say that any given person supporting any given character may have a different view than another person supporting the same character. Both sides of the issue are pretty common to find.
Finally, there’s the argument that all characters so far have been third party. And for the most part, I think the last 2 will be as well (as much as I don’t want them to because there’s a very small pool of third parties left I care about). This is perhaps the biggest “deconfirmation argument” for Porky, as well as all other first parties. However, I do think it’s (very slightly) possible that the final 2 are both Nintendo characters. I don’t think we’ll only get 1 Nintendo character though (unless it’s a bonus outside the pass). For me personally, I view the last two as both third party, or both first party. For this argument, there is no real evidence either way, as everyone (so far) is completely in the dark about who the final 2 will be.
I’m not trying to attack anyone’s opinions with this post, just trying to reinforce/state my own thinking, as well as some other people’s as well. It’s acknowledged that first parties are sleeper candidates for the final two spots too, so I’m also not saying any of what I’ve said is hard evidence. Just the way I look at things and that, while unlikely, these things still have the possibility of happening, however small.
