The hype has diminished a little. Given how the meta population has tripled, metahumans are less unique, and therefore a little less exciting. However, the big names (Atomight and Mechanima, for example) still have quite a bit of merch, and anyone who's stuck out likely has some knock off figures available for sale somewhere.

They're not advertised like they had been back when the government had been sponsoring them, but that's not going to stop people from developing toys of their favorites.
