Erm there is a game update which I ignore and it then takes you through to a system update...
And yes I am on 5.5.1! So I suggest some of you get off your high horses and give facts!
Had you got your head out of your ass and actually read some of the few dozen BOTW related threads on this site alone, you would of seen that there a hundreds of people who have been playing the game since it was leaked midweek. I myself have had it installed since thursday and have reinstalled it since it was officially released.
Im in the uk so thats another reason i knew you were talking bollocks mate
