The LEGO fan website FBTB.net has uploaded many, many, MANY photos and even videos to their Flickr account from the 2012 New York Toy Fair.

While Kingdoms and Castle are notably absent, things look quite good for fans of castles and medieval creations in general.
High on my list of interest are the Lord of the Rings assortments:http://www.fbtb.net/2012/02/12/lego-toy-fair-2012-lord-of-the-rings/
But also the surprise return of classic movie-monsters in the theme Monster Fighters:http://www.fbtb.net/2012/02/12/lego-toy-fair-2012-monster-fighters/
Plenty of goodies to love in these with elements that will add great detail to any builders collection of parts and ideas. Cannot wait to see them in stores this Summer.
Thank you for looking!
