Hot Wheels has announced a couple of new Batmobiles releasing later this year. While there are no official images of them yet, better to have it on your radar so you do not miss out on them. Both groups come out in October of this year, but they will be available at certain retailers. These are specifically part of the HW Entertainment series.

Mix 4-The Bat–The Dark Knight Rises New Die-cast Chassis! Available at select hobby retailers
