[Rumor] Bayonetta 3 releasing in 2018

[DélioPT]

It's not releasing in 2018.
If it was planned to come out during summer 2018, Nintendo would have told this. Not only that, it would have shown footage of a game that was about to be released in 6-7 months.

Also, the "now in development..." part points at the game being early in development. Like MP4.
