As expected, set 76052 Batman Classic TV Series - Batcave (€289.99) is available today for VIP members on the LEGO Shop. This set will then be available to the general public from March 1st.
The bad news of the day: No polybag 30603 Batman Classic TV Series - Mr Freeze offered for the purchase of this set.
No need to panic, if this polybag was given away during the New York Toy Fair to people invited by LEGO to a presentation of its stand reserved for the press, it should logically appear in volume soon.
LEGO has a habit of giving its guests a few exclusive gifts during the New York Toy Fair, but these are usually very limited edition products made especially for the occasion.
The polybag 30603 is not one of these products, it is a classic bag, bearing a standard reference and as such it will logically be available in the usual distribution channel of LEGO products, perhaps even from March 1st, the global release date of set 76052 Batman Classic TV Series - Batcave.
Obviously, this polybag is already for sale on eBay for a few hundred dollars...
