With the custom movesets that means there really can't be anymore clones, right? Also I've never played the Fire Emblem series but Robin looks cool as hell to play as, can't wait to try him out!
No, the custom move sets isn't the same as what anyone actually wanted (Palutena/Mii Fighters aside).
All characters (besides Palutena/Mii Fighters) have 3 different options for a special move (making for a total of 12 special moves per character). However, these 3 options only differ in
properties of the moves -- the animations themselves never change (Palutena/Mii Fighters aside, again).
An example of this was shown in the Direct months ago with Marth's shield breaker. His default neutral B doesn't move on the ground -- however, one of the options you can choose for it is so the neutral B slides across the ground a set distance once you've let go (charging it might affect its distance, not sure yet).
While that does change how the move works, the animation and likely the knockback/angle/damage are all the same.
Another example of a property difference for a special is Kirby's neutral B. While the default for Kirby's neutral B is to suck people in to copy their abilities one of his options as a custom move for neutral B is to... basically make it so he's breathing ice (or blowing it or something). The move is still the same animation but it does something different.
However, again, this only affects special moves. Everything else about the characters aren't customizable. So you can't change Lucina's normal moves (the A moves like forward smash, up air, down tilt, etc.) Which is what determines how much of a clone a character is -- how many of their A and B moves are literally using the same animation?
Basically, even with selectable special moves for each character the character is still going to be roughly the same. Toon Link will still be mostly a clone of Link, even if his bombs have a different on-hit effect with one of the choices for customization because moves like Forward Smash and Down Air are still the same from Link (talking from animations here, not properties). Toon Link is the closest character possible to a Melee clone in this game*.
I hope this makes sense.
*: I say closest because he is the same as he was in Brawl, only 3 aerial moves differ from Link substantially (Fair, Nair, Bair), Up smash is one hit instead of three, and down tilt is a poke rather than a swipe. Only 5 moves differ in animation and one move is actually a new move (up smash). He borrows
a lot from Link.
