I hope Marth's "tip of the sword does more damage" stays, that's what made him more interesting/skilled to me
It's pretty much his trademark design aspect so I'd imagine it'd stay. I just wonder if they'd redo his hitboxes to be more Melee like (much more length, but sweetspot is necessary for KOs with up and down smash) or keep going in the Brawl direction (reduced length but has a vacuum effect, can KO from any part of the sword with the tippers being stupid stronk).
Brawl Marth's nair was my favorite button in the series thus far because of the changes to his sword hitboxes and properties on tippers.
