I wonder if the yurt in the background is a planned set? That'd be a great item, especially if it had a Mongolian family included, and we'd be buying a lot of those to make nomad villages.
I'm wondering the same thing too, Martin. That yurt could be used as a round hut for various "barbarians" for the Roman and Medieval themes as well as African huts.
Regarding the new castle, as others have posted, it looks like it's System X albeit with large pieces, so I don't know how customizable it will be. I really like the heraldry, the new shield shape, and the knight. I also very much like the portcullis, which is a first for Playmobil, I think. The walls are a new mould, being of rough cut stone and not the neat blocks of the previous castle. I'm not sure I like this, but it's something different.
I like the new house a lot. It's more in the French style, which is a nice change. The klickies, however, are modern, so I'm guessing the furniture will be the same, which is a shame.
The new spy theme looks like hideous Fischer Price!
