@Haiil I could'nt found any information either, but I know Fractured will have different kind of conquer features where sieges are one part. I presume this has not been opened much yet.
I guess somekind of siegecamp system like you mentioned could be quite close what we will actually see. I hope we can see different size of sieges depending the lvl and size of the object. Meaning variations like 10v10 , 20v20 , 50v50..
In addition, I hope we can see siege weapons as well. Maybe attackers can craft these with lead of carpenter(s). Same with defenders, they should also have chance to make some preparations like reinforce walls and build own siege weapons as well. And because taking advantage of environment is a thing in Fractured, maybe some oil can be spread over the battlefield and set up people to fire for example.
