The People of Syracuse/Messena
The Ligurians/The Boii
The Bastarnae

And possibly:
Carthaginian Rebels
Roman Rebels
Eastern Greek Rebels
Western Greek Rebels
Add Pergamon, to that. As long as the map is not extended further to the east you won't get to see an Indian faction, if we may believe what EB stated a while ago... That was as far as the team was concerned in regarding to 0.8, but given that the main Indian faction of that time seems to be the Mauryan Empire...

If there are more provinces in the EB2 campaign map, then I guess there will be more in the Sahara desert and the Russian Steppes.
