Amazing! Thank you for the info. Also, I suspect that at least one part of the drawbridge defense will have the little 2x1 technic bricks like the other castle parts so they could be put together if you wanted. The modular building is actually something I really like about the new sets, I was thinking about buying another king's castle set and making a bigger castle with a full inner keep.
Here's hoping for some dwarf and orc/troll battle packs. :D
