'Andor' offers regular Imperial Army, TIE Pilots, Stormtroopers, Phase II Clone Troopers, K2 Enforcer Droids and Death Troopers -- all figures Hot Toys can pump out without much fuss. Given what's in the pipeline I'd say maybe Stormtrooper and a Death Trooper, TIE Pilot teased and left in limbo forever.
As for the rest ... Cassian packed with his 'family droid' ... Luthen, Dedra, and Mon Mothma would be a minimalistic offering of some key players but Hot Toys is capricious and unpredictable, so if we saw Andor, Luthen and Dedra it'd be pretty shocking.
They didn't do much with Rogue One so I'd say they may well do less with this.
