I've resigned myself to Samus's fate being forever shackled to the N64 moveset.
My bigger disappointment is that Ultimate Samus didn't take any cues from her appearance in Samus Returns, as not only is that suit awesome as hell, but it was wasted on a tiny 3DS screen and deserved the HD treatment.
Incidentally, when the roster inevitably gets cut down for the next Smash, my only request is that the N64/Melee characters that they do decide to keep get a makeover to put them more in line with 4/Ultimate's newcomers; Shooty Samus, thoroughly decloned Ganondorf, Ness with a non-janky recovery, etc.
