Wonder if having him as Zato-1 is their way of ending him and Millia's story? As in Zato-1's resurrected and has had enough of Eddie's shit.
And to add to that, Zatoichi is a famous series of samurai movies and tv shows about a wandering blind swordsman.
His name is pronounced Zato One in GG I thought. (is even spelled as such in one of the games)
but it is a reference to Zatoichi
I remember this dude had some crazy ass combos in one of the GG where he was the best character. Him, Jam, and Slayer are my favorites.
You are correct, and they only renamed the character Eddie / came up with a story to justify it since the original voice actor passed away and Daisuke thought it was best to do so out of respect.
Up until now there always was a "and more!" text at the bottom right of the character select screen. It's gone now, so that may be indicative the full roster excluding bosses is there for this first iteration. I'd maybe expect additional characters for the console version.
