A new polybag has been found! LEGO Marvel Superheroes Electro (5002125) minifigure polybag has been found on ebay and sold for $190! The minifigure is from the amazing spiderman 2 and has apparently been given out at KidsFest in Virginia USA and it is possible it will be given out at future events. I don't know if it will be available as a promotion but if it was I would think it could be some time next year.
