This morning its now out that the Tomb Kings FAQ has been updated. Now it appears that its only a small update, mostly regarding skeleton chariots and the Casket of Souls. So while its a small, I tend to go with any update to the FAQ's as a good sign Games Workshop is trying to keep up with us.

Here is the link

I looked only briefly to see if anything else was updated, but did not see anything. Let me know if you find other updates.
