The latest issue of Game Trade Magazine has a full page ad for the new Innsmouth Horror expansion, and here are a few things o be gelaned from what I can see of the game pieces:
Two of the new investigators are shown, and one looks just like Calvin Wright (and it appears he has a "fish hand" on his shoulder, but that could just be my imagination).
The other investigator is a blond woman playing the violin. I wonder if she is related to Julia Brown, the violinist in the current CoC lcg expansion block.
There are no new Outer Worlds. Instead, there appears to be some sort of track -- I think this might refer to the new Reef mechanic.
Each "location" in Innsmouth has a modifier underneath the location circle. This obviously also deals with one of the two new machnics (either the Reef or the Innsmouth Look).
There is also a new creature color -- white or grey. This is the border of the Child of Ib monster (hoping I remembered that right -- I don't have the ad in front of me right now).
And, as wel already know, Bokrug is in the game. They showed the back of two other "Ancient One" cards, but I am not familiar enough with the mythos to identify them. And both of the Heralds are said to be "the toughest the game has ever seen (paraphrased quote)."
May can not come fast enough.
