Pretty much all the updates for exanima is the ground work for sui generis so you should expect thaumaturgy, talking to npcs, maybe small destruction, true stealth, it is just a bunch of stuff.
If you bought the beta which costed somewhere around 30 dollars you will get both exanima and suigeneris. If you bought it when it just showed exanima alone or on steam you will have to pay for sui generis separate.
You know thaumaturgy is my third most anticipated feature first being reactive a.i, and ranged weapons...now that I think about it probably is stealth.
