I'd sure like to think in the years to come we will have a true "golden era" of Castle. Being far too young to experience the first one, (born in '96, the early Castle set I ever got was KKI or early KKII, I was more of a Town fan when I was a kid though) I would love to have not only that title attributed to a period of time, but also just to HAVE that period of time where awesome sets with fantastic pieces come out left and right.
Kingdoms was obviously a step in the right direction, and while LOTR is going to focus most on the action side of things, I think we can expect a wide variety of new weapons and helmets.
I am afraid of sharks. Just so you know.
