I was going to write a list of hopeful LOTR sets, but it turned into one idea for a large set and a sort of minifigure checklist :D The ones in bold are coming out in the first wave. Could someone confirm if Merry and Pippin have made an appearance in the prelims?
Definite Minifigures (Due to importance to plot, etc) and some to have more than one appearance:
Frodo (Coat design
and Dishevelled design)
Sam (Coat design
and Dishevelled design)
Merry (Coat design and Rohan armour design)
Pippin (Coat design and Gondor armour design)
Aragorn (Ranger design
and King Design)
Gandalf (Gandalf the Grey design and Gandalf the White design)
Eowyn (Shild Maiden design and Armour design)
Theoden (Robe design and Armour design
Also, these characters should appear, although their secondary designs would be a bonus:
Bilbo (FOTR design and ROTK design)
Boromir (Standard design
and Armour design)
Faramir (Ranger design and Armour design)
Elrond (Robe design and Armour design)
These characters would require new moulds (And Sauron would have to be taller than regular figures):
The Witch King
These characters could appear, depending on the sets Lego produces:
These creatures should appear:
Treebeard and Ents
Watcher in the Water
Armies that should appear:
Gondorian Soldiers (Citadel Guards and Guards of the Fountain Court if I was being greedy :D)
The Other Eight Nazgul
The King of the Dead and the Army of the Dead would be good. As see-through minifigures are impossible, is it possible to make minifigures entirely out of glow in the dark plastic?
Perhaps that list is a little too hopeful, but I don't think any of those characters are unreasonable, all being main or supporting characters in the film series.
Anyway, the set I was thinking of was the Shire. It would be like Diagon Alley, in that it has three main buildings with accessories, as well as a large amount of minifigures. However, as the Shire is Hobbie-sized, it would be a smaller set in terms of piece count and price. The main buildings of the Shire focussed on in the movies are Bag End and the Green Dragon, the pub. The third building would be the Mill, as it is one of the few buildings in the Shire )I think the only other one that springs to mind is the Green Dragon that is not build as a hole in the ground. It's a water mill, that could fit any number of play features as well as compliment one of the smaller accessories, the bridge.
I think that would look rather wonderful in brick form :D
The other accessories would be Bag End's Gate (No admittance except on party business), a tree and a party tent with food, drink and a bench. A few animals (I remember pigs and chickens from the movie) would also be included. The Green Dragon would have a bar, tables and beer barrels, and Bag end would have a writing desk with the Red Book, a fireplace, a chest, a kitchen and a dining room.
The minifigures included would be:
Gandalf the Grey, Frodo (Coat design), Bilbo, Sam, Rosie Cotton, Gaffer, Ted Sandyman and two other Hobbits. These could be Merry and Pippin, or two random Hobbits (I think I'd prefer at least one more female Hobbit, or a Hobbit child)
