The third season of Transformers Prime is apparently being branded as just Beast Hunters, and the first two episodes have been revealed for March 22nd and 29th in America (on the HUB channel).

Not sure if the title for the first episode is meant to be "Darkmount", which is Straxus' Decepticon base from Gen1, and the name Hasbro gave the Classicverse Straxus toy.

Season Three, Episode 1: “Darkmouth, NV”
While Optimus struggles to survive after Megatron’s destruction of the Autobot base, the separated members of Team Prime try to reconnect. Airs 3/22/2013.

Season Three, Episode 2: “Scattered”
The Autobots search for signs of each other, but start to lose hope while the Decepticons welcome a key player to their ranks. A win for Wheeljack may ultimately lead to an Autobot defeat. Airs 3/29/2013.
