I do not think it is going to be the case, but the best-case scenario is that you separate mp and sp, like in DAI or ME. But usually, only the devs with big studios and a long bucket can do that.
I agree that when you try to make your OC a MP experience, you have to make some concessions to make the game pace more fluid and you have to cut some things. And forget about to stop talking to npc, reading books or crafting because you make the other party members wait too much.
In DaO2, for example, the banters between party members and involvement in conversations were minimal. They also changed the thievery mechanics since the beta. In beta the guy you robbed call his friends and they search for you as a mob, but in the final version only the robbed person does that, and it is very easy to evade.
