I just got finished watching the teaser for TFU2, and I have to say, I'm eager for gameplay right now.
By the way, the Star Wars Wiki doesn't have an official name for the beast, so I can only assume they've created this beast simply for the game. There's nothing more on the game, but there is one burning question:
Why the fuck does Marek look the way he does in the trailer if he died in one ending, and became a Sith Lord in the other wearing fused Stalker armor? What the shit, LucasArts?
