Season 2 is confirmed and will also be the end - it's a confirmed 24 episode series. Count me in on thinking it's the best Star Wars series to date. Tony Gilroy is a genius and considering Rogue One is probably a top 3 (maybe 4) Star Wars movie of all time, it's not entirely surprising.
It's nice to not have a break from the constant stories taking place in the desert about jedi with lone wolf and cub plots. It's a drama that my wife, who doesn't do sci-fi, actually enjoyed a lot because of the Tony Gilroy genius and the phenomenal acting chops.
