I agree with Nick on the Ysalimirri dealio there... Think that's the acknowledgement of their existence and that's it. Don't think Thrawn would've passed those by Vader/Palps given their capabilities against the Force.
I love seeing Thrawn put into the show... To me he was always going to be "around" anyway since I liked him and consider him part of Star Wars regardless of what the highest bidder has to say.
If those imp droids were Dark Troopers, and they sure seem like they may be, I hope they don't piss around with that story much either. And piss on that Star Wars mobile game's attempt at rewriting anything from that storyline (I don't think they did, but freemium gaming is meh).
The chick from KotCS is already an action figure, if you had her and an extra Deena Shan from Force Unleashed handy. The head swaps perfectly for those who want to basically make that Imperial Governor without much effort. The KotCS girl's figure may actually have value now.
