Does anyone have any info on this Batman figure?

(Dvd is there for scale reference)

I bought this gigantic figure at the swapmeet this morning. I have been looking online for info on it and can't find much. All I know is that it's a Mattel produced Batman figure made in 2008 for probably the Dark Knight movie line. I found similar 30inch Batman figures online but none of them have the backpack with the bat wings made of real cloth. The Back pack is awesome with real padded straps and has a working ripcord like feature which pops the wings out when pulled. The wing span is very impressive, I couldn't get the entire wing to fit in the pic. There is a VIN type number on the tag on the backpack and the same number is molded into the back of the figure. The woman who sold it to me wasn't much help, She said she bought it at an estate sale and doesn't know anything beyond that. Any info on this incredible figure would be very much appreciated.
