Found the Armored WK wave yesterday at my local TRU (Iowa) to my surprise. The WK rang up 8.99 as opposed to the others, but I think this is because he's still in the computer from being part of the original first ROTK assortment last year. Just be sure to double check when purchasing.
On to my thoughts:
Merry in Armor: One of the best figs of the wave. Great likeness, great sculpt, great articulation, great everything. Probably my favorite of the group, really.
KOTD: Lots of fun, actually. Pics do not do him justice. Lots of articulation, a great sculpt all around, and the GITD thing works gangbusters.
Faramir in Armor: Fantastic likeness, great sculpt and articulation. Two problems: he has a huge button on his back for an action feature that does not exist, and his arms are oversized. The arms I can get over, and you can hang his silly helmet on the button.
Armored WK: So big he barely fits on the card. Great sculpt, one of the best. His robes restrict a lot of movement offered by his articulation, but all he has to do is stand there and look bad ass, which he does. He holds the sword and giant mace well and towers over Eowyn.
All in all, probably the best wave of figs in a long time, maybe ever. Can't wait for more!
