The new lines of castle and space are intended to be a "return to roots" effort by LEGO. Both lines got direct suggestions and input from Ambassadors... and even hands on design by 2 (Grand Admiral concepting out the only spaceship in the new mars line).
Well, the jury is still out on how classic the new mars line is. But when we saw some preliminary pics of the castle, we all said about the same thing... "EWW CASTLE." No no, that was later. We all said, "man that really has the spirit of old castle, I like it, I want to get it for the good parts." Every one said it.
Well I just happened to see the 7093 set available and went ahead and got it. It's got lightning bits, an 3vil wizard with 3vil hat, new robot arms, and white exoforce arms. Plus new bley slopes. It's really designed well and was a fantastic fun build.

my website has the pics (but they didn't exactly order correctly on upload)
