okay my bad,in the first first what i mean is another sub-fiction,not mean sisters of battle are a option.

Well that's going to happen...but later.

Creating models takes a lot of time, it's a post launch thing.

okay stop this topic,that's not what i wanna dicus here

I just wanna talk about some other fiction,dont know why i wrote sub-fiction in the first myself,and i think i cant edit the title now

Well if they were to ever add the Sisters, it would need to be part of a huge update that introduces at least one other new faction as well. Maybe the Tau, the Dark Eldar, or the Chaos Demons.

So the plan from the Devs is to implement all the Factions of 40k over course of the game. We just have to hope that they don't run out of money or loose the playerbase and we need to bring a huge a mount of patience and time....but the intention from their side is there. I assume if the game is released late 2016 we will not see a new faction before 2018.
So I guess if you really want to play exclusively female character you unfortunately have to stick to Eldar until then.

or donate about 150 mill to bE and see all our dreams come true

That's right, it sucks !
They have a small team and a small budget, then they could do a crazy game !
It would raise money to help them.

Actually I believe that's an update for two Rogue Trader Era adventurer models (they were also SoB forerunners).
