The U-Wing and TIE Striker are gorgeous designs and both fit with the brand of Star Wars and their faction. I love the uniform designs of the Imperial ships and I love the rugged look of Rebel ships. As for originality the Striker is the first TIE we'll with moveable wings design for atmospheric flight and the U-Wing is the first ship with a swing-wing type design and the Rebels first shuttle.
These ships are going to attract a lot more sales of X-Wing as, unlike a lot it of (mainly Scum) releases, billions of people will recognise these instantly and not just us geeks.
