I think the reality is that Smash Bros Speculation is going through a minor identity crisis: is Smash a general gaming crossover, or is it a Nintendo crossover?
Prior Smash for Wii U/3DS' DLC, there really wasn't a debate that Smash wasn't a Nintendo crossover. Yeah, there were a few non-Nintendo characters, but they were so vastly outnumbered by the Nintendo cast that the theme of "Nintendo meets Nintendo plus a couple of guests" was pretty unambiguous.
I think the foundations of this debate started to emerge during Smash for Wii U/3DS' DLC and Ultimate's base roster. Here, we got third parties in a greater quantity than ever before, with each set of newcomers having three third parties each (

for Wii U/3DS DLC and
,
, and
for Ultimate). However, most people still saw Smash primarily as a Nintendo game. The number of Nintendo newcomers still outnumbering the non-Nintendo newcomers, third parties often having first party characters revealed in between them, and Richter/Ken being echoes helped send the message "Yeah, non-Nintendo is the exception, not the rule".
However, starting with the Fighter's Pass, this is when the "Smash is now a general gaming crossover" camp emerged from basically one reveal:
. Now, Joker is awesome, but he's also the biggest hard-left we've ever seen occur in Smash speculation. Dude broke a lot of conceptions over who is and is not eligible for Smash. Not only was he far newer than every other third party in Smash, he was almost far more obscure than the other (non-echo) third parties. The only character who matched Joker in being a relatively recent, more obscure non-Nintendo character is Bayonetta, who was largely seen as an exception due to having Bayonetta 2 funded and published by the Big N itself.
Thanks to Joker, the floodgates seemed to be open. You no longer had to be a Sonic or Ryu to be a non-Nintendo character in Smash, anyone from a reasonably popular game was a viable candidate. Compound this with an ambiguous "the other fighters will be like Joker" comment from Reggie, it really seemed like the sky was the limit. The Smash community has a bad habit on bunkering down on a handful of faces that are deemed likely, the expectation of Smash now being focused on more than just Nintendo self-perpetuated itself. With Joker being followed by three other characters from non-Nintendo companies, it really seemed like Smash was undoubtedly a general gaming crossover...
However, looking at who we got, we didn't really get any hard curveballs like Joker.
was probably the most conventional third party we saw in the pack. While Hero is technically a very new character due to Eleven's recency, having alts based on other characters from the NES and PS2 situated Hero as a legacy character. Likewise, Dragon Quest is a massive franchise with a strong tie to Nintendo, making Hero far closer to Mega Man than Joker.
came from a smaller franchise like Joker, but they were also far older and has extremely heavy ties to Nintendo, reducing a lot of the surprise that came with the bear and the bird.
was another character from a more lowkey franchise, but his legacy and fame within his own genre divorced him from the curveball factor of Joker. Now,
and ARMS are giving us back to back Nintendo characters. It's impossible to know where FP #7 and beyond will go, but the wild west of possible character choices that many thought would come after Joker seems to be less and less with each choice.
So, is Smash a gaming crossover or a Nintendo crossover? Honestly, like with many things, the truth is somewhere in the middle. There is no doubt the restrictions on third parties in Smash have loosened as time has gone. However, beyond Joker, we still aren't seeing the wild "anyone goes" picks that folks in the "Smash is a gaming crossover" suggest we should be seeing. As such, I always get surprised when people are perplexed that there's still a call for Nintendo characters. It's great that we're seeing more and more diverse characters join Smash, but the series isn't going to completely abandon its foundation overnight. Even after Ultimate's DLC, the focus on Nintendo first and foremost is still present.
