Once again Brickset has posted a list of the new polybags for the coming year. Unfortunately there doesn't seem to be much information to go on besides the picture of the sets themselves and some potentially incomplete parts lists. So this year I won't post links to all of them, just the ones I find the most interesting.
30188 Cute Kitty. Don't laugh. I see 1x1 Technic Bricks, Clip Plates, Bar Plates, Lever & Bases, cheese slopes, and some other things that microscale mecha builders like.
30226 Police Helicopter. There's been a Police Helicopter polybag before. I have one in my review pile right now. This one looks better, it even has more parts.
30244 Anakin's Jedi Interceptor. Star Wars polys can be tricky. They can be limited releases like the Umbaran MHC from last year, or suffer under the heavy "Star Wars Tax". I like the colors and parts on this one though.
30263 Spider Crawler. The Legends of Chima polybags can be overpriced. This one looks to have some interesting parts at a decent quantity.
30302 Spider-Man. Good parts, good colors, good quantity.
30300 The Batman Tumbler. 57 pieces and it builds a microscale Tumbler. Awesome.
30189 Transport Plane, 30246 Imperial Shuttle, and 30247 ARC-170 Starfighter also have good parts and good piece counts.
As always, YMMV. Hopefully we get solidified information soon that will allow better decision making.
