The Clone Wars TV series returns

I didn't see this coming! I'm excited but pissed it's probably gonna be on Disney's forth coming streaming service.
I have some questions, like most of you, My #1 Question is who's the Mado standing next to Ahsoka??? Could it be Sabine??

 I wonder if we'll Caleb Dume?
Question #2 Who's the dude standing next to Anakin and Rex in the hangar with the back pack?
