Nefarious was due to release today on the Nintendo Switch, but that will no longer be happening as planned.
The developers have announced via the Switch news app, that the game has been delayed to October 4. The reason for this is that people who received an early version ( including this writer) have reported gameplay bugs and issues. The delay will be to give the developers time to fix the game and make it right.
If you pre-ordered the game on the eShop, you can still get the game today. Just be aware that there are bugs that need to be fixed still.
