I'm not so keen on all future Larian games being co-op ready. Co-op creates a number of design challenges and restrictions, and those limit what you can do with the story. You have to take into account a lot of stuff, including players splitting up.
There is also the balance between freedom and motivation to take into account. Those are opposing forces in games.
Co-op is something not to be taken lightly in game design. It's not something you add just to put a bullet point on the box. It's not something you add merely because another game had it. There has to be a reason for co-op.
