Same, especially since people have been so vocal on how they wished echoes were handled better. I think they'd pull a Ken for additional echoes, in the sense that there's lots of changes to make them stand as its own character, which you can see with my predictions below.
For me, it's...
Dixie Kong -
- Add Peach float with propeller ponytail and new throws.
Gooigi -
- Mostly the same, with changes to jump height and movement speed.
Shadow -
Change Up-B to Chaos Control, similar charge time to Zelda's teleport.
Rock Howard -
- Easily the most drastic change from Terry. There are a lot of changes that I don't think I could cover all of in a single post.
