The Sith Interceptor is looking slick. I like the Desert Skiff a lot, too. I would love to get my hands on Jabba's Palace but unfortunately it will probably be too pricey for me.
Some of the sets look pretty odd, though. I really can't understand the reasoning behind yet ANOTHER Jedi starfighter. It was never a compelling design to begin with, so why do we need eight different versions? I don't mind updates of more iconic ships, like the X-Wing, because it's great to see improved versions of such a recognizable design. But this? Why?
I also don't really understand the KOTOR ships, either. Although I love the Sith Interceptor, the other two (including the exclusive) look like something out of Gradius rather than Star Wars. The figs are nice, but they just don't feel Star-Wars-y to me at all. At least the Interceptor bears resemblance to the Empire's aesthetics.
The Sub is well designed for sure, but I don't really care for Episode I sets and I refuse to spend money on a Jar Jar Binks. Call me biased.
As for the planet sets, they're decent, but the only reason to get them is for the figs.
I hope we see the UCS B-Wing soon, I'm dying for that one.

Thanks, Grogall, you wonderful man you.
