You mean, in this next update there will be other mercenary bands??
Yes :)
For the upcoming update they will only appear in the context of events and contracts where they take a special role (you have to fight them, they chase you, you talk them etc). Our plan for the final release is to have them acting more independently, but we will see how far we get with this, as there are lots of other things to take care of.
Cheers!
