I don't have a problem with the Forgotten Realms [...]
For me it is about too much of a good thing. I like the FR, even love them. Lots of good memories having adventures there. Nowadays we mostly travel between planes, so the FR just pops up now and then and that is perfect.
Golarion is interesting because it is one world with many settings on it. Numeria isn't Cheliax which isn't Osirion...
The FR could have some of that potential (Chult isn't Thay which isn't Cormyr...), but now everything is set on the Sword Coast. The only AP that I would buy from WotC would be if it was set in Selune's Tears on the Roc of Bral*. Never gonna happen, sadly.
Since Perkins said he was writting storylines for the next seven years, we might in for a lot of Sword Coast for a long time.
*Everything is getting Realmified. Rise of Tiamat was a DragonLance adventure. Elemental Evil was a Greyhawk adventure. Rage of Drizzt sounds and looks like Planescape. So Bral would be set in the Realms. Not that would mind since I palced it there in the first place and it needs an update. I bet the next AP is undead themed and Vecna is the summoned baddy at the end.
