The first two eps are out in the US...It's a two parter called Ties that Bind.
Jesus from the Hilltop is in this, he's on the front page of the 3rd ep.
The first ep is killer and you're thrown into the chaos from the start almost. It's way better than Season 2
Also if can remember your options from the past, the game will let you choose Clem's backstory before you start the new season or there's an option to transfer what you did in the 2nd season to your telltale account and then hook it up to 3 from any device
