Oto island/1954 sequence in the new movie.

According to Empire magazine there will be a pre-title sequence that takes place in 1954. So what can we expect from that scene? Since it is a pre-title sequence during 1954 it will most likely set up some back story for the film. I think it will either be about a nuclear test creating Godzilla or something to do with the original legend from the 1954 movie. Will Oto island come into play here? Because in the original film Oto island was where they discovered his name according to a legend/ritual on the island. So what are your thoughts on this?
