I'm simply compiling what was in a previous beta thread with some recent developments. As you might notice, I'm super excited about the game so I thought I'd share some of the known info on upcoming units with everyone!

We know we have more base classes coming as well. In Here Alex said "We have five new playable base classes shipping with chapter 1 of the Saga which means a ton of new advanced classes."
Base Class (?): Mender (upcoming!)
Base Class (?): Berserk (upcoming!)
In this image (although quite fuzzy due to low quality) we can see some of upcoming units along with some Dredge, which have been confirmed to (at a minimum) be opponents in the single player saga
Dredge Grunt
Dredge Warrior
Dredge Tank
Dredge Slinger
Dredge Elite
Dredge Elite Slinger
This image contains (from left to right) Rook and Juno (two charactars in the single player saga, note that Juno's name may change prior to the Saga hitting, and Rook has been described by the developers as a "Hunter" in the Forum chat window), a possible Berserk, a centaur, a possible Dredge Grunt, and a Backbiter.
In Here Alex said "About the berserks, I don't want to say too much but they will be a new base class... and they're Varl."
Later in the same thread Alex stated "centaurs have been in our lineup for quite a while. They'll be a race new to the game in chapter 2, though, so don't expect to see them in the first release (plenty of other cool stuff to get to, first). "
Arnie then followed up with "they probably won't be called "centaurs" as that's from Greek mythology. These people are designed off the Icelandic Ponies that the viking rode. Surefooted, shaggy haired...etc. They are the one race, so far, that will look like they came from a different culture. That of the celts. "
Here we can see our Raiders (originally named Axeman) but while including the soon to be released Grudgeweilder! Just look how amazing the artwork on the Grudgewielder's shield is!
Provided in the recent Single Player update FOUND HERE we can see images (from left to right) of what probably is the soon-to-be hunter, a spearman, a male mender, a female mender, and a possible Berserk. Each of these models will be used for characters in the single player saga, but will also be the same models eventually used in Factions as well!
We dont know much about Menders. But Here Alex said "As for Menders, I'm really looking forward to adding them to the game. They will play differently from other classes in a key way that should be really interesting. "
Arnie followed up a little later describing them with "They aren't quite wizards as they use a much more subtle magic which 'weaves' the fabric of creation. We're basing them on the Norns from northmen mythology. I would not think they would jump up off the screen and attack like a Dragoon in FF, but they may be able to pick a tile and channel something for the next round to hit it. "
