Sounds about right
A Reddit user by the name of OldSoul2 has posted some images that he supposedly received from EA in which they have accidentally revealed the date for the first Nintendo Direct of 2018.
The text highlighting the Direct comes from a slide in which the company is describing their plans for ‘Fe’ and upcoming showings and release date:
The leak also includes information about ‘A Way Out’ a PS4 game which was announced at the E3 back in June. The leak itself hasn’t been officially confirmed, but this goes in accordance with other rumors that have been going around, and would strategically make sense for Nintendo to do so, as it would help them lay out their plans for 2018.
