Here are my thoughts on the new release date.
Pros:
More than enough time to perfect the script, to have meaningful and well fleshed out characters and dialogue.
Redesign the monsters to make them realistic and grounded and at the same time respectful to their original designs, similar to what they did to Godzilla.
Cons:
The excruciating long waiting time for Godzilla 2.
If Godzilla 2 is 2018, so that means Godzilla 3 is 2022 ????

Was bringing back Edwards really that important that they had to wait for him to be done with Star Wars?
