I found this over the weekend (along with one of the other new DC Superheroes sets) and worked on a review of it last night: http://www.thepicreview.com/2014/01/lego-review-batman-man-bat-attack-from.html
The set comes with a black suited Batman (we've seen him before), a New 52 Nightwing, and the first ever Lego Man-Bat. Plus, there's a Batcopter and a glider for Nightwing. Pretty nice set that retails for around 19.99.
Having Man-Bat makes me really want Lego to bring back Killer Croc who hasn't been released since the original Lego Batman line.
