I will admit this probably is not the best timing, but personally, the idea of a Southern Victory has been intriguing to me, and I love the idea that the guys who are doing Game of Thrones are also doing this. Plus, take a look at the description on HBO's Medium account:
It definitely sounds like they're painting this new CSA as a horrible thing, and they seem to be building to some sort of major slve rebellion, and it definitely implies that some of the protagonists will be abolitionists.
Overall, I'm looking forward to it. Not the best timing, but I'll be tuning in regardless.
