But I'm not liking how a lot of the controllable Final Smashes are now looking to be uncontrollable.
Other changes (speaking as I haven't been able to watch the videos yet, just check on articles):
Mario has Cappy, but possibly just as a cosmetic touch.
Link's bombs & Final have changed.
Female Pikachus are available.
FALCO'S FINAL HAS CHANGED THANK THE LORD.
Ryu now always faces the opponent in 1-on-1.
Samus can charge in mid-air.
Dedede's Final has changed again.
Damage percentages now include decimals.
Female Pkmn Trainer now available.
Pkmn Trainers can swap mons without penalty (i.e., no more stamina meter)
Cloud's Limit gauge is always visible.
Robin's sword/tome gauges are now visible.
Villager's pocket is now visible.
Giga Bowser has been buffed. Run.
Monado Art selection is streamlined.
Pit has a new Final again.
Samus has a new final.
Olimar's helmet cracks with damage. Not sure if that affects his performance.
Finals are now "get right to the punch", whatever the crap that means.
Wario-Man has been altered.
DK has a new final. Still bongo-esque, but more Jungle Beat & less Konga.
Giga Mac has been altered.
Mega Man's Final now includes Proto Man & Bass.
Palutena "has a set special attack for each move". (No more customs?)
ROB now has a fuel gauge.
Inkling: Inked opponents take more damage.
Inkling: Ink can run out & must be recharged in squid form.
More ATs can be KO'd, & those kills count towards your score in timed matches.
Waluigi still an assist trophy, because sometimes I get what I want in life, & what I wanted was Waluigi not to be playable.

New ATs: Midna, Burrowing Snagret, Bomberman, Squid Sisters, Rodin
New Pokeballs: Solgaleo, Bewear
New items: Healing Field, Launch Star, Bomber, FAKE SMASH BALL
New stages: Moray Towers, Great Plateau Tower
Returning stages: Green Greens, Kongo Falls, Princess Peach's Castle, Great Bay, Shadow Moses Island, New Pork City, Saffron City
Omega mode returns. New Battlefield mode with it.
Directional air dodging. Excessive dodging shortens invulnerability window.
Ladder attacks.
Short hop attacks.
Attacks do more damage in 1-v-1.
Cube controllers & Amiibo are still compatible.
Paula & Poo show up for Ness's final (to summon the Starstorm, maybe?). Likewise, Kumatora & Boney show up for Lucas's.
Pichu is still a masochist.
Zelda has a new Final.
Ganon's Final is now OoT-based.
RELEASE DATE: DECEMBER 7th
So far, the only confirmed new characters are Inklings & Ridley (& Daisy as an echo), but we've got almost 6 months for more info.
And remember, "I'm-a Luigi, number one!"
