At the end of January The 60 Years of the LEGO Brick (40290) set will be available
However you can now download the building instructions now. The advantage of this is seeing the instructions early you also have the parts list of the set.
The set doesn’t seem to have any exclusive pieces besides the printed 60th anniversary 2×4 tile. However, there are some fairly rare new pieces. The 60 Years of the LEGO Brick (40290) set will be available from January 28 – February 14 with a purchase of $125 (other currencies may differ) or more at LEGO Brand Stores and on Shop@Home. *Source Brickset*
