Our Friends at Marvel Toys write in to tell us: 

Select Wal-Mart stores in the Denver area are receiving an early shipment of Legendary Comic Book Heroes. The shipment includes both Series 1 & Series 2 and should hit shelves in the next couple of weeks.

Legendary Comic Book Heroes will be more widely available in other regions & retailers closer to fall.  But if you can’t wait, I hear Denver is lovely this time of year!  Get in line for full sets with variants, and be one of the first to build Pitt & Monkey Man.
Happy Hunting!!

These are already starting to show up on Ebay from a seller in Hong Kong so they should be along shortly…. and they are awesome!
