3rd party software development in 9th gen in the current circumstances.

[Jizz_Beard_thePirate]

It happens pretty much every generation hence the "cross gen period." They will develop for ps4/x1 until the next gen has a reasonable amount of sales. The switch will only come into play if the publisher thinks it's worth putting in the extra effort as it will get harder and harder to port down to the switch. Hopefully the rumored switch pro or switch 2 will be out before it really starts going.
