Will SW use magnetic north for compasses?

[AndyJWest]

I think that given what Oleg (or was it Luthier?) recently said about the way SoW models a spherical Earth, modelling the difference between magnetic and true north shouldn't be that difficult. Whether it is that significant on a relatively small map like the BoB one is arguable though - magnetic compasses are prone to larger errors than the minor differences you will see over the map, I'd have thought.
