30277 First Order Star Destroyer, 30278 Poe's X-Wing Fighter and 30279 Kylo Ren's Command Shuttle should all make for decent IO ships or starting points for IO ships. As might 30346 Prison Island Helicopter, 30421 Ninjago Polybag, and 30471 Helicopter. (Of course I've already reviewed Poe's X-Wing.)
30371 Knight's Cycle, 30372 Robin's Mini Fortrex, 30373 Knighton Hyper Cannon, and 30374: Lava Slinger from the Nexo Knights line along with 30422 Another Ninjago Polybag and 30446 The Batmobile could all make for interesting Frame designs.
This year doesn't look as good as previous years in terms of polybags, but there are several sets without pictures in the lineup.
