Wal-Mart seems like it will be the spot for Funko in 2017. There are 2 new 3-packs that are headed exclusively to Wal-Mart, and soon. The first one will be based on the Cantina and include Momaw Nadon (Hammerhead), Greedo, & Ponda Baba (Walrus Man). RebelScum.com posted the following image.
While I was searching for this on Walmart.com, I came across this listing. This looks to be an Episode III 3-Pack including Tarfful, Unhooded Emperor, Utapau Clonetrooper.
No word on when either of these sets will be showing up, but we will surely keep an update on this anticipated sets!
