... and, no, it is not a campaign setting but some form of regional guide book.
It's the Sword Coast Adventurer's Guide which looks like it's going to follow the example of 4E's Neverwinter Campaign Setting and focus on a smaller area. And I mention the Neverwinter Campaign Setting because that seemed to be almost uniformly praised even by those whose natural reaction is to hate FR products.
But it's also interesting that, as expected, there's no campaign guide for FR. I don't think this is going to win the Candlekeepers (ie, diehard FR fans) back but I suspect it will, like the Neverwinter Campaign Setting, have fairly broad appeal especially if the CRPG Sword Coast Legends turns out to be a good product.
While I am not interested in 5E or the 5E Realms, I will still be grabbing this as the Sword Coast is a big part of why I am a fan of FR.
