I asked for a Coke in this waffle house in Tennessee, and they gave me a Pepsi.
I asked why and they said "Pepsi is Coke here".
Originally I had typed a longer response which had addressed that. I lived in Georgia for a while, and I remember there being a few places where 'Coke' was used a universal word for soda in general.
Anyway, my point was that I'd be confused if I opened the Pathfinder Beginner's Box and found D&D 4th Edition Essentials. I understand the OP's point, but I do not view 'D&D' as being synonymous with rpg. Likewise, I view Pathfinder as a different brand -even if it's a brand which is extremely similar to Coke 3.5.
I had a friend who tried snorting Coke once. He said the ice cubes kept getting stuck in his nose.
