My general speculation:
Supposed to have better shields than t65. Possibly a weaker/smaller chassis, so less hull? ( 3 shield, 3 hull )?
Faster than t65, so a native boost for sure. White Boost (of course)
White 3 Tallon Rolls ? If so, then potentially Red 2 Tallons as well.

SHIP ABILITY:
Built-in 1.0 Primed Thrusters
That, or maybe built-in 1.0 Integrated Astro.
Last good option, in my opinion, is ship ability of "Weapons Guidance" from 1.0.

Astromechs:
Follow suit from the Rebel conversion:
Named version = better than generic BB Astro.
...so multiply 1.0 BB8, and you might get...
BB Astromech , First Order & Resistance Only.
When you reveal a Blue manuever, you may perform a Barrel Roll action.
New BB-8? : Resistance Only. When you reveal a Blue manuever, you may perform a boost or barrel roll action.

Generally not liking the idea of a flippable S-foils card for the T70s..... I don't think they need them.
I'm sure with a new articulated model, similar or identical abilities for s-foils title are incoming.
