As a fan of all things Dras I support this notion.
But as a self proclaimed realist I don't think it will happen unless they are running out of other shit to talk about or a dev swings by this thread and is super bored.
The salt marsh is counterpoint to the bog as the biome in question directly correlates to having access to the ocean, and as it's not something that is relevant to the entire community as not all servers have one biome or the other I don't think we will see anything on the bog Or the salt marsh, much to my displeasure as I've been a fan of the bog since the idea was planted in my head.
Anyways, I'd love to see info, +1, but I'm not holding my breath.
