I dont want another hedgehog.

What strikes me most in ssf is the quality, so I do not expect in the future has a LOT of characters as the crusade. By the way, is great crusade game in grating the characters because in gameplay, we can not praise both

Shadow and Knuckles were in the first ssf, why not go back to them?

I'm using Google Translate , so sorry

I am speculating that for the next update, Bowser and King Dedede will be revealed alongside Isaac. I could also see an unlockable character happening too, which was similar to some of the updates when Captain Falcon and Black Mage were unlockables. I could see Luigi being unlockable.

Also, I speculate Luffy because he is really popular and it would complete the Shonen Trilogy.

But the Trilogy is already completed. We already have 3 anime characters. I think you mean a Shonen Quartet.

Mr Incredible was in the first game too, this isnt exactly the best logic bruh.

Plus theres the whole thing of oversaturating the cast with a third party series. Really goes against the console quality smash game target. The cast of this first game was honestly kinda dumb (i mean really dumb) and its not really in the game's best interest to have that happening to ssf2

Not a speculation, but I'd personally like to see a different FE main character. It would be nice to see someone from the japanese exclusive games.

As long as its not another sword guy

please, no more swordmen, this game have alread: Link, Meta Knight, Llloyd, Marth, Ichigo, Sora(key) and maybe Issac.
It needs more villains like Bowser and Ganondorf(with an original moveset), and maybe dark matter (I don't know why, but this idea came into my mind)

It seems like Dark Matter is getting quite popular huh.
I used to complain a lot about swordsmen characters but I find them okay, as long as they have unique properties.

There is 6 sowdmen in this game and smash 4 has 7 I think one more in this game won't hurt anything

Shulk and Ike , maybe this is the last swordsman

So we have:
Azrael(cut);
Blade(cut);
Blue(cut);
Copy X(cut and replaced by Megaman);
Kratos Aurion(unknown status);
Sasuke(unknown status);
Vegeta(cut and became a background character);
Renji(cut and became an assist trophy);
Riku(unknown status);
Spikeman(cut);
Pit(unknown status);
Shadow(unknown status);
Knuckles(unknown status);
Snake(unknown status);
Zero(unknown status);
Diddy Kong(unknown status);
Luigi(unknown status);
Bowser(unknown status)

Who should be cut and replaced?

I vote for Sasuke, Riku and Kratos. Mostly because they'd seem to saturate the game with 3rd and 4th parties.
I'd say something similar about Shadow, mostly because of how saturated the game would feel with 4 Sonic reps.

No one else should be cut/replaced until we are actually told, 'Yes, he/she is cut from the games final roster.'

smash 4's cast is also much, much larger.
