According to the Beast Kingdom booth moments ago at Comic-Con's Preview Night, "about" 50 of these "Egg Attack" Boba Fett figures will be released per day.
The 6" (15.5cm) figure has over 28 points of articulations. They retail for $80. While inspired by The Empire Strikes Back, the jetpack is from Return of the Jedi. Also, the gauntlets are from Jedi, but with Empire colors. (Whoops!)
For more info and photos on the figure, see our Bounty database entry.
