It's definitely marketing choices and I agree they'll want to push hard their own corporate identity and not seem like a sister company of MR. Studio Scale, while not trademarked or whatever, is in the minds of consumers, an MR product term. If you brought some fellow collector's to your house and said look at my Studio Scale Tie Fighter, odds are someone would comment on how good MR did with it and you'd have to correct them. Studios Scale has association with MR and if you use the same term for your line the connection is going to be there. MR burnt some bridges and as eFX lays some new ones, they're going to have to go different routes to get people to cross those bridges.
