On Japanese Shinkansen bullet trains, you hear the announcement say "We will soon be arriving at [the name of a station]." Is there any difference between
"We will soon arrive at Tokyo Station." and
"We will soon be arriving at Tokyo Station."?
I wonder why the announcement uses "will be arriving" instead of "will arrive". Is it more formal or something?
I also wonder why announcements on trains do not say
"We are going to arrive at Tokyo Station." or
"We are arriving at Tokyo Station."
Would it be informal or odd for announcements on trains to say "We are going to arrive..." and "We are arriving..."?
