For those that pay attention to everything, we can deduce that the name of the new clan will be 'Polit' which means Political in German as I read.
So we can assume that this Clan will probaby be of a political orientation, and guess that these are the ones that run and control Clint City.
How many characters can one come up with for this clan? I'd be very interested to see.
I'm taking an educated guess and saying that their bonus might be something Support: orientated.
We can prove this:
For instance Rosen's bio reads:
'Ever since she was little, Rosen has lived at one with nature, especially with the sweet little birds that like to eat from her hand and sing with her. But times are changing and nowadays, to stand up to the Polit and other clans, you’re better off with a giant fighting sparrow on your side!!'
Notice how it says ' to stand up to the Polit and other clans'
Therefore identifying the Polit AS a Clan. By association.
Funnily enough the Polit were mentioned a long long time ago, though nobody really paid attention at the time.
Vanssar, possibly one of the first few card release's BIOs begins:
'Within the first few days of joining the Polit army,'
Something that the Staff had plans for all along?
No, I don't think so, just a clever/conveniant way to tie all the cards together.
All in all an interesting move by the Staff, that will, if it works, systematically tie all the Clans together in one mutual hatred of this yet to be released Clan.
Although from what I've seen, the clans go into a rotation based on alignment: evil, neutral, good. And given that Berzerk is neutral (granted chaotic-neutral), we're in line for another good-aligned clan which the Polit doesn't seem to be. Though I kinda like the idea of Polit being more of an "up to the player to decide" kind of thing.
