Here's what the excerpt reveals to us about both Godzilla, MUTO and the film's plot:
Godzilla is amphibious
Godzilla is male, not female
The atomic blast from 1954 did not kill Godzilla
Godzilla has been asleep in the Pacific Ocean for decades
The MUTO is an ancient creature, from the same time period that Godzilla existed in
Both Godzilla and the MUTO were natural enemies
Godzilla's atomic ray is consistent with previous films, though a rare occurance. Possibly because it does him harm or depleats his energy. The weapon may be more of a "last attempt" to survive, rather than a casual tool of destruction
Something resurrects the MUTO, which threatens Godzilla's survival
There could be more than one Godzilla in hibernation deep in the ocean
Possibly the last of an ancient species of giant amphibious creatures that evolved at a time when the surface of the earth was over 10 times more radioactive than it is today. GODZILLA can convert his radiation stores into a violent, focused exhalation of atomic ray. Rarely seen, but spoken of in antient Pacific Islan myths. 'Gojira' was last spotted in 1954 when the U.S Navy encountered and attempted to kill him with an atomic blast in the Pacific Ocean. Since then, the giant creature has been living in the deep ocean - until a threat to his survival from an ancient foe forces him to reappear.
