Brave and the Bold is the newest version of the Caped Crusaders adventures and the series basically teams Batman up with a new hero-of-week every week. The choices for team ups tend to be more obscure or lesser known characters.
Personally I am holding out for a Plastic Man figure myself.
Mattel was demonstrating a Batmobile for the line which converted into a Jet and featured several firing missiles. The show is a lot of fun and adults will enjoy it as much as kids I suspect. The toys look pretty good to.
