at the end of the day i'm a fan and surely without me/us there is no career for Grant or Rebellion so surely it's in the interest for all party's to come to some agreement that benefits all of us.
I'd imagine the legal shenanigans of the nineties just provided Morrison and Millar with a handy way of ensuring Fleetway didn't make a killing flooding the US market with cheapo reprints of their not-very-good early work on the back of their newfound fame. Morrison's name and reputation are so well established now that can't be a concern anymore, and in the case of
Zenith there isn't any worry about the quality of the material.
I'm sure it's in the best interests of both parties to cut some kind of deal where Morrison gets a handsome share of any reprint profits and Rebellion agree to treat the character and the existing material in the same way as Halo Jones - rather than farming Zenith out as a house character to up and coming writers looking for a break, as they appear to be doing with another of his creations. That seems a bit cheeky, but I suppose it makes a point.
