In December, Lego announced that they had secured a licence to produce LOTR themed sets. The first sets, due this summer, will feature characters and locations from the LOTR trilogy. Later in the year, we'll also get hobbit-themed sets to coincide with the release of The Hobbit movie.
Here are the provisional details of the first sets:
•9469 Gandalf Arrives – Minifigures: Gandalf, Frodo
•9470 Shelob Attacks – Minifigures: Samwise, Frodo, Gollum
•9471 Uruk-hai Army – Minifigures: x4 Uruk-hai with a siege crossbow, x1 Rohirrim Soldier, x1 Rider Of Rohan with his horse
•9472 Attack On Weathertop- Minifigures: Samwise, Frodo, Aragon, x2 Ring Wraiths
•9473 Mines Of Moria – Minifigures: Frogo, Gimli, Legolas, Boromir, x2 Goblins, x2 Skeletons, Cave Troll
•9474 The Battle Of Helms Deep – Minifigures: Aragon, Gimli, Legolas, Theoden, x5 Uruk-hai
I think these sets could be very popular with collectors and investors - and a few may even actually get played with as toys by children.
The other 2012 Lego releases which caught my interest were a Star Wars Lego game (Battle for Hoth), and four (possibly 5) further Heroica sets. All of these look like Autumn/Winter products, but there's a chance they might be earlier.
