No need to spoil anything.. All eyes will be on Apple and the new iPhone 7 and new Apple Watch...
Nintendo should piggyback off Apple and Sony events. Lets say the general press does a article on these press events. They talk about Neo, near the end of the article they are likely to add Nintendo has also revealed they have something cooking and will be shown next week. If Nintendo dint announce a reveal date they probably won't even mention Nintendo in all the articles.
