A list from a Barnes & Noble computer was posted on the Funko sub-Reddit this week, and has a full list of upcoming POP! lines. These are NOT confirmed by Funko as of yet, so we do not know for sure if they are legit.
Home Alone (Kevin, Marv, Harry)
Jumanji (Dr. Bravestone, Professor Oberon)
Masters of the Universe (Battle Armor He-Man, Battle Armor Skeletor, Stratos, Mer-Man, Beast Man, Orco, Evelyn)
Stranger Things (Skateboard Max, Joyce)
Elf (Buddy, Jovie, Papa Elf)
Hellboy (Hellboy, Liz Sherman, Abe Sapian, Nimue, Rasputin)
Marvel vs. Capcom 2-Packs
Mortal Kombat (Kitana, Raiden, Liu Kang, Sub Zero, Scorpion)
Snow White (Snow White, Doc, Grumpy, Happy, Bashful, Dopey, Sleepy, Sneezy, The Evil Queen)
Kingdom Hearts (Sora, Kairi, Riku, Heartless)
How The Grinch Stole Christmas (The Grinch, Max)
DC Heroes (Bombshells Supergirl, 8-Bit Batgirl)

If they are true, then I am very excited for more He-Man and the Marvel vs. Capcom 2-Packs! Hopefully more on all of these soon!
