Pretty much. A topic I've danced around a lot when it comes to insider rumors is that a vast majority of the characters that come up are, well, "Boomer picks." If you're not familiar with the slang, in gaming terms it's basically Millennials and older. Were you a child or teen when the first Smash Bros came out? Congrats; you're a Boomer! The youngest character that typically comes up? Steve? from Minecraft. That's 2009 if you count the various Betas, 2011 if you don't. There really isn't anybody younger and most are honestly late 90's, early 2000's, so when I was in elementary school and middle school. Ryu and Steve? are basically the outliers that come up, while most were "born" during the days of the N64, PS1, PS2, GameCube, etc.
To a degree I feel like this is deliberate. Aside from the "mandatory promotional picks" like Incineroar and Byleth, most of the additions have overwhelmingly been "Boomer picks." Aside from those two, "modern character wise" you have Inkling and Isabelle who are crazy popular anyways and Joker. Everyone else has a pretty long legacy whether they were super wanted for Smash or not. This is why I fold my hands, look the Smash fanbase in the eyes and ask "was your character decently wanted for Smash by 2012? If not, I honestly wouldn't hold your breath." To rephrase this, if your character wasn't an up and comer before Smash 4 was announced, I think a safer bet would be a future Smash game and not this one.
