We've seen a couple of teaser images for the upcoming Tolkien theme, and as others have pointed out, these are basically LEGO versions of some of the Peter Jackson movie posters:
This, of course, raises the question of what will be the next poster. These seem pretty obvious candidates. BTW, was there a movie poster for any of the three movies that focused just on Sam? I can't find any, which is, IMO, a pretty good indicator that Jackson largely missed Tolkien's point. Okay, I'll save a movie rant for another day.
If they break away from the pattern of character close-ups, these are some others that I'd love to see in LEGO. Of course the third one would answer the question I asked before about how they will do the Ring.
I've shared this image before, but this is a good time to describe it in detail. Back in 2004 there was a movie poster contest on Lugnet. Here was my entry. There were several movie posters that were collages of images, and LEGO could do something like I did here. BTW, in case you're wondering, the faint image of the Ring in my poster is the top of a LEGO key, faded out in Photoshop.
One last, that would be fun and old school:
