Over on Eurobricks, somebody posted a link to a
high-resolution version of the picture.
Of the Dwarves, I think I like the looks of Balin the best - certainly his beard will be the most useful, and I think it's be mostly-compatible with a couple of TLC's newer hairpieces.
If you look closely at Bombur, it almost looks like he's got a belly piece and a beard with a printed shirt design. That would fit with certain other rumors I don't know if I'm allowed to talk about, but it makes him a little less useful overall.
I've never liked the "
Yooper" look for Bofur, but at least his head and torso look fairly generic. Actually, all of the Dwarf torsos we can see look fantastic.
Dwalin's hair/beard could go either way - ideally I'd like to get ahold of one in person. On that note, I've read some speculation (again, Eurobricks) that these are the minifigures from one set in particular, probably the Bag End set. That makes sense to me, but based on these minifigs I fear that the pricepoint may be closer to Weathertop than the Uruk-Hai Army.
