Finally got around to watching the new trailer last night. Good stuff. This season looks action packed...can't wait for the Kamino siege. Good to hear they are making a point to move things forward plot-wise and character-wise. I really do hope they have a clear exit strategy and endgame in mind for the show though, and aren't just treading water ala LOST. If the show is planned for 5 seasons, stick to that and sketch out the arcs accordingly.
Now to the obligatory complaining.

I am troubled by the ongoing infusion of comic/novel/video game EU into the show. I get that it's a shrewd marketing ploy on the part of Hasbro to cross-pollinate the various lines and force suckers like me who love TCW but hate the "other" EU stuff to buy their crap. And it works. I ponied up the dough for my Kul Teska like a good little consumer, all the while wishing they just could have called him Wat Tambor and been done with it.
I just think it blurs all sense of continuity with these ongoing "mash-ups". It used to be I could just watch the show having seen all 6 movies plus the animated 3D TCW film, and I had all the background I needed to grasp the plot to its fullest extent. Now I'm increasingly baffled trying to figure out what the hell is a Quinlan Vos and a "Nightsister".

(Bad Manga rip-off on those chicks BTW)
The other problem I have is that they are just overloading on too many characters now, particularly villains. Do we really need ANOTHER Sith lackey? I've lost count of how many bad guys there are at this point. They don't seem to have a problem killing Jedi on that show, why not spread a little death around on the Separatist side? A little purge now and again helps keep things manageable. (see: Heroes)
And just stop with the ridiculous names already. SAVAGE OPPRESS?!?! AYFKM? Yeah, the French inflection really makes him sound bad-ass. It's not even cute or clever anymore, it's just lazy. That schtick stopped being funny about 8 Bond movies ago.
Inane rants aside, I do really enjoy the show and am very psyched for the upcoming premier. And I'm buying all the toys just like they want me too.
