The more I am looking at these two vehicles, the more I am liking them as opposed to the vehicles that were released for TFA. The reason is, both the X-Wing and TIE were cool designs, but not very different from what we saw before (which is still a GOOD thing when it comes to the continuation of the OT). But the TFA vehicles were also cheaply made. Especially the X-Wing.
Since the U-Wing is totally new, I find it interesting enough to make the purchase - unless I see reviews beforehand revealing it's a cheap piece of junk. The TIE striker, I think is a wicked design and really fits in wonderfully with the Imperial designs we all know and love. It's a definite buy - I just hope the silly nerf feature is easily removable.
I showed these to my son last night, and his reaction was, "whoa!" So that's better than his reaction to the TFA vehicles too. He also seems to like the AT-ACT. And with this movie having more of a "warfare" theme - I think there's a good possibility that the kids are going to be a little more interested in the toylines as well.
My prediction on these two vehicles is the U-Wing will end up sitting a lot longer on shelves. Hasbro should produce more TIEs than U-Wings. But I'm not sure that kind of obvious logic has even crossed their minds!
