Updating a post from earlier today: Amazon is listing the Complete 1960s Batman TV for pre-order in both a regular DVD edition and "limited edition" Blu-ray.
No details on either, yet, but we'll keep you posted.
The DVD set is listed at $179.74 (regular price $199.70) while the Blu-ray set is $188.98 (regular price $269.97).
I'd imagine the price, at least for the DVD set, will drop a bit. Amazon does have its pre-order price guarantee, though, if you just can't bear to wait any longer. The means you'll be credited for any difference if the price drops between the time you order and the time the set ships.
