I've asked in the d20 Publisher's forum what the latest is on d20 Blackmoor.
I'm definitely looking forward to CSotIO. I just got the Wilderland's Gazatteer and am loving it.
Interesting putting Freeport in the Wilderlands. I also think Bluffside would fit nicely.
Now that I think of it, there don't seem to be nearly as many new settings coming up as there were last year. Last year in a relatively short period were released Midnight, Diamond Throne/Arcana Unearthed, the Warcraft RPG, Scarred Lands: Termana, Dragonlance, and later on Dawnforge, Morningstar, and the Wilderlands. and several more I can't recall.
