Interestingly, he listed some licenses he was interested in doing for the future:
If you could create a set of Pint Size Heroes for any license, which would you pick?
Please don’t make me pick just one. I would love to do a set for Hanna Barbera, many more in the Marvel Universe, the best of Cartoon Network (Powerpuff Girls, Samurai Jack, Dexter’s Laboratory, We Bear Bears, Teen Titans Go etc.), Masters of the Universe, Thundercats, and Adventure Time.
There's also some more concept art (heads) of characters not made into figures...but could they be hints at future PSHs? I spy more DC and Marvel, He-Man, Thundercats, Star Wars, Muppets, Scooby Doo, etc.
