Uprising: Curse of the Last Emperor question

I just discovered this game today as someone in my city is selling it with Archfiends expansion. Forgive me, I'm trying to read up and catch up as to what is happening after crowd funding. I don't really understand all that I've read though.

Is it worth waiting for the next edition, (is it a reprint?) or is it just adding to the base game corebox that I could add to later on? Thank you. I will play solo & coop. Thank you.
