A source close to Thomas Tull stated that Legendary plans for Godzilla and Kong to join forces in Godzilla vs. Kong. It won't be a rushed mess like Batman vs. Superman, this movie actually has several films setting it up and many years before its release.

And what do you mean by "a Kong wouldn't look right in 2020?" That doesn't make any sense.
