Given that there are still a good 3.5 months left till release day, think TOR/BS/Harriet will release any additional content, be it paid for or free? I suspect the answer will be no, but I really wish it'd be a yes....

Two chapters apparently, one written and one audio. We do not know if a third will be involved in a Great Hunt.

No Great Hunt. That was already done, with the Cadsuane thing from the notes. Instead, you got the excerpt from chapter 11.

Wait...what Cadsuane thing?

During the Alloy of Law release there was a Great Hunt which revealed Jordan's notes (either partial or complete) on Cadsuane's past and nature.

 

Edit: Peter, thanks for the confirmation about the Great Hunt.

Wait...what Cadsuane thing?

 

Here it is if you want to check it out...

It's probably worth adding that they usually appear once a month. The prologue was due Oct 2, so I expect we'd see chapter 1 early Nov and chapter 2 early December.
