Definitely liking the look of Inquisitor's TIE Advanced. It blends together a number of looks, from Maul's Sith Infiltrator in the wings, to the ROTS era Jedi Interceptor, and especially Vader's TIE Advanced X-1. That kind of blending continuity is a great thing to see!
The AT-DP looks pretty cool, too. I would love to see the hatch open, but I get the sense that it's a one man vehicle based on the size of the pod.
The Phantom seems alright. I wasn't expecting vehices right out of the gate for REBELS, but this is definitely welcome. Still, it seems like the Ghost is the more important ship in the context of the series. Perhaps we'll have to wait to see how the show does in it's first season before Hasbro commits to producing a Ghost vehicle? If they do it, I would expect that Hasbro might have a price target of $80 - $100 for that particular ship.
Also noteworthy? I think we'll be seeing a REBELS stylized TIE Fighter at some point. The graphics on the mockup box for Inquisitor's TIE Advanced have a standard TIE on there, and we've seen a number of TIE's featured in some of the pre-production art that's been released. I think that standard TIE would be a no-brainer for this line.
