I saw those the other day. I think they look very cool. It'll be nice to get a partner (Buzz) for Draa, and hopefully the ARF is an indication that some Ryloth figures (Keeli and Di) aren't far behind. The BARC speeder looks to be a minor retool, using the 2005 deluxe sculpt with landing gear with a full front portion. It's possible that the AT-RT has some additional leg articulation, but I'm not holding my breath... it's nice to know that the Buzz and BARC set isn't a total repaint.
Also, judging by the shots of the backs of the packages the upcoming "mini-rig" vehicles might not be too far off.
