The Betrayal of Calth and Burning of Prospero are officially gone, so if you wanted one and see it in a store.... its a good time to get it. They are gone, and although they leave it open that more could be made, consider it gone.
Thank you for sending this in... from a Reader on Faeit 212

Unfortunately this product is no longer available to order and it was removed from our web store once the last of the stock of it was sold.
This does not necessarily mean it will never return but it won’t be available for the foreseeable future, if it does return then it would be announced on the Community site.
I'm sorry I cannot help more directly and if you have any further queries, please get back in touch.
