Amigo's confirmed; a Eurogamer article mentions playing as him here. Akira's also mentioned in one of the blogs about the game, but no word on Jacky.

[KMetalmind]

Thanks for the answer!!! I was sure Amigo was confirmed and I though Akira was mentioned somewhere... Updating this now

[MightytheArmadillo]

It'd be odd if Akira was in but not Jacky this time around. Besides, Jacky was the one driving, Akira was only ever used as an All-Star move. Akira didn't even appear to really want to drive anyways lol

[KMetalmind]

I think the same, but I can´t say if he´s confirmed too

"Why am I in this car?"

This.

I mean JACKY is the real driver. As far as I know, that's how he got his fortune in the first place, by winning races!
Akira is there because he's the face of Virtua Fighter, and apparently a good friend of Jacky, so the Jacky&Akira combination makes a lot of sense, imo.

Ryu and Ken are inseparable.

[MightytheArmadillo]

Ryu and Ken are inseparable.

(and imo much more likeable than Akira and Jacky, but I've always been more of a Street Fighter person than Virtua Fighter)

[KMetalmind]

Me too. I don´t care about them being on S&SASR and I never play as them, but I don´t dislike them either.
