They are starting a different trilogy with a different writer before the first book of the previously mentioned trilogy has even come out?

Well, it is by a different author. I assume these trilogies should be viewed as isolated events.

Multiple simultaneous stories rather increases the verisimilitude of the mythos. I like it!

I love that more Arkham Horror fiction is in the works but why the long wait for Ghouls?
