It has always been said that you start off with the standard race, then at some point, via the research you do, you become a rebel or a loyalist. The only way to stay as a vanilla original faction is to stop researching. Since everyone else will still be researching, you eventually will have to continue or you will be exterminated by superior forces. So at game start, there are only 3 factions, by the end, assuming everyone has done research, there are 6 factions.
You forgot to indicate how many players in the figure you created. Anyways, the non loyal/rebel unresearched standard faction cant be considered a faction by itself if thats what you mean.
I don't think they ever said there would be 9 factions, even if there are technically. They said there were 2 new subfactions per race, but some forum users took that as 9.
If you look at the new interview, there are quite a few hints that they will differ in ways far beyond the titan.
Ill be sure to check thanks.
