I think it's probably since they weren't expecting the EA to be such a huge success. There are some veterans here who were around during DOS2 who thinks Larian just gonna ignore everything and do what they want, but I honestly doubt it. We'll just have to wait and see.

"74.85% of you stood with the Tieflings, and 25.15% of you sided with Minthara. Good outweighs evil, it seems."
