The Lego Hobbit Boardgame has appeared for pre-order on toysrus.com. I know it's probably stretching the limits of what constitutes a new 'castle' set, but personally I really like the lego games. Both for parts and for game play. Some great micro-builds.
Both photos are currently private, so I'll comment on what I see now.
Looks like the microfigs are going to be great, as usual. So it's like Memory, I suppose. The tiless (2x2) appear to be various faces and perhaps a map? Those could be great for paintings and (obviously) maps, respectively.
When I realized it was a 'memory game', I thought: "an over-engineered card game!"
But then I look at all the awesome parts, and I drool a little.
