I received some news from LEGO Ed regarding the new version of NXT-G. Anyone who orders from LEGO Ed today forward will receive the new 1.1 in August. They will ship 1.0 when the order is placed and then 1.1 when it comes out in August. FLL is apparently going to operate in the same manner. Whether you have a single copy license or site license, you only need 1 (one) upgrade copy.
