Update related:
An Adam West hosted promo for the DVDs is happening tonight or early next morning depending on your perspective of things. I stumbled across it last night. I didn't expect that they'd have Adam West hosting it because it's listed in the same way as a paid program is. But he is hosting it and it's on WGN at 4am titled "BATMAN exclusive!". Now it is a paid program for a 64 episode classic collection but if you go to the site they also offer the full series with the exclusive extras. If you don't get WGN the promo may be on another channel.
