So if I am following the updates correctly there is 10 slots, with 2 filled by Pergi and the Numidians.
Now there was a hint about a Nomad faction which I am assuming is Numidia and was there a hint of another occultis Hellenistic faction? So we have 8 slots left, one of which is probably another Greek faction (and I'd put the Acropolis on it being Syracuse).
My guess would be we'll see some more holes filled, eg the Mittel Europa gap (1 or 2) the steppe vacuum (1), and maybe some balancing in Spain (1 or 2). Remember this is Europa Barbarorum.
Round out with a Caucasian/iranian crossover in Iberia or Atropatene and we have one slot left for my beloved Mauryan satraps with their lovely elephant generals (and culture limit problems solved..somehow..please).
That would be an awesome alt-rock band.
Alternately an EB period NBA franchise based in Alexandria, to go up against the Seleucea Grey Deaths and the Arretium Spammed Triarii.
