This is not the case with "it will become fashionable" because I believe it has become fashionable for Xbox to always change something on their console since the initial version presented. But apparently this was the last change that Xbox did, because the console has already entered the production line.
This information was provided by Yusef Mehdi, the Xbox marketing chief, who disclosed that Xbox has undergone a hardware upgrade before going into production. This improvement was in the CPU which increased its performance from 1,6GHz to 1,75GHz.
Xbox One received some criticism from its audience in their presentation that they considered PS4 to be superior in processing and hardware. Since the announcement that Microsoft has tried to improve some aspects of it to be able to have the best console in the market. But it seems that this was the definitive change since it went into production with a probable release date also for September.
