My thoughts exactly. Not to discredit highly-desired characters or anything (especially as I've wanted Bandana Waddle Dee for the longest time now), but I've always been even MORE taken with the 'oddball' choices of Smash. It honestly bugs me when people say 'There's no more big 1st parties to add to Smash' or 'There's little value in Nintendo adding their own characters anymore'.
In addition to it being FAR more financially viable for Nintendo to do just that (adding more of their OWN stock into Smash), I honestly don't know if I'd be THAT excited for so many 3rd parties being added. I know it sounds crazy to say, but I feel like the hype I'd get from 3rd parties being added would become a little dulled over time. 1st parties, on the other hand?
Heck, give me Chibi-Robo, Ashley Mizuki Robbins, Kyle Hyde, Angelique Noir (Style Savvy 4), Lark, Mona, Goku (Yuyuki), Urban Champion, Bubbles, and the like, and I'd honestly find THAT more exciting.
At this point, I assume I'm at least well-known around here for being far-and-away more interested in Nintendo's own catalogue of characters than the 3rd party side of things.
