I just got my Series 2 stuff!
Havent had a chance to open it yet, but everything looks much better than Series 1, and Series 1 was fantastic.
There are tons and tons of great pictures at KBToys of upcoming sets. The Fell Beast set looks great, and should be near perfectly scaled. It also has a Ringwraith rider (you can see his arm if you look closely).
AOME is shaping up to be an unbeatable toy line.
Mosnab, since you are just getting started, I'd definately recommend AOME. It's smaller, just as much detail, and you dont have as much catching up to do.
