Will more Kaiju be featured in the Monsterverse?

Do you mean by more new kaijus or more Toho kaijus?

Monsterverse Kaiju.

^

 ah ok then I could say yes!

It all depends on whether or not the MonsterVerse will continue after Godzilla vs. Kong.

^Correct.

And for everyone here--The word "kaiju" is already plural.

I could see some less significant original kaiju showing up.

Throw MG and KG in there and see how tough Godzilla and Kong really are
