Two Questions about Godzilla vs Kong

1.How likely will there be a 3rd common enemy monster in Godzilla vs Kong? If there is a 3rd common enemy monster, how likely would it be an original kaiju created for the Monsterverse (like the MUTOs and the Skullcrawlers) or a Toho creation (like Bolliante or Destroyah)?

2.Will we see more of the creatures on Skull Island in Godzilla vs Kong not seen in Kong Skull Island?
