I am actually really really excited about these!
Starting with lake town. I dont think the price is too bad, considering that it has the same number of minifigs and almost the same piece count, and the same price as warg attack last wave. Plus the master of lake town and thorin with that torso are probably both exclusive. I am thinking we will see bard and the lake town soldier again in a smaug attacks set, or battle of five armies set, but I could be wrong. The boat looks cool to me, even though it is similar to the vikings boat, I think it actually looks a bit better. There are a few rare or exclusive pieces I spotted, like the shield, some dark green pieces, and the masters hat. All of the minifigs are AWESOME looking, although bilbo is starting to get overused if you ask me. The set its self is just very cool looking, with the touches of snow here and there. I love boats, and docks and stuff too (one of my favorite sets is the midgard serpent vs viking ship set) so this is great for me... And I am also a total lotr/tolkien geek.
I like Thorin coming out of the barrel after Bard collects them.
On to azog! I like this figure! He will certainly stand out (and up) among my other figs, but I think he looks very good over all. The tall legs are a nice touch to give him some extra hight, although I do think they are unnecessary. The head mold is also very cool, and looks just like azog if you just look at it, not the fig as a whole. Not that I am saying the fig does not look like azog, just the head mold is extremely movie accurate. However, I am not sure I like the neck and chest parts attached to it. I still think it looks ok though. His printing is excellent in my opinion. The barbed hand piece looks great too! The mace I don't like so much, I will probably build a replacement for it. All in all I really really like this figure!
Now for speculation on the other 4 sets in the wave.
1) I am really hoping for another mirkwood set, centered on Thranduils halls, including the throne and its surround, Thranduil himself, Legolas, Thorin, and a couple elven guards. This would be a small to medium sized set, at around 150-300 pieces, for about 20-30 dollars.
2) next I hope we get the interior of Erabor, with smaugs horde, Bilbo, and the great beast himself. Possible they could include some pillars and stairs and stuff all around. Size depends on whether smaug is brick-built or molded.
3) Beorns house. With Gandalf, bilbo, a dwarf or two, and Beorn (human form with tall legs like azog, and molded bear form). Hopefully also some farm animals. Then beorns house, with the big tables and chairs and everything. Medium to large sized set, probably cost 60-80 $.
4) I dont know! We could get a dol goldur, another scene from the first movie, or a preview scene from the third movie. But on second thought, I have read several places that leo has announced that the regular azog figure will be in a set this wave, so he could be included in the mikwood one, from what we see in the trailer, or maybe the Beorn one, depending on what happens just before this scene in the movie.
All in all I am getting really excited about this years Hobbit wave, and the film... The marketing strategy is working.
