If Vader's arms, elbows (it looks like it) and shoulders (not so sure but hopefully) are articulated then he might one of the best figures ever. I really like the look of him.
The Snowtrooper is so so, not spectacular. They could have went a little further with the articulation but I'll still be getting some. The officer insignia, might detract a little from army building.
I am dissapointed there is no Luke pics, maybe later today as they do mention him in the article!
