Not really since Sakurai has been putting a good number of lesser known or less popular characters over the really known or extremely popular ones since Smash 4. 64, Melee, and Brawl were pretty much nothing but Nintendo's heaviest hitters while Smash 4 was when the more obscure or lesser popular characters started to get in like Robin, Lucina, Shulk, Corrin, ect. Not to say those characters weren't popular, but there were and still are a ton of characters that are way more popular than them that still hasn't made it in yet.
