In a recent Reddit AMA (Link), the developers of This is the Police answered a few questions and made a few comments. On of the interesting ones made was how the development experience for the This is the Police differed between platforms. While the technical difficulties faced when developing for the Switch was challenging, the overall experience was better due to the limited amount of red tape when developing for the Switch.
Porting to Switch was more challenging because of the hardware restrictions but the toolset, documentation and review process made up for it. We had to do a lot of optimizations to make the game run smoothly on Switch, but red tape for publishing on PS4 and XB1 and other issues took a lot of time and energy from us. I would say the experience was: Switch > PS4 >> XB1.
Also when asked when This is the Police would be released for the Nintendo Switch, the developers did not give a definite release date, only that it will be coming very soon.
We are aiming really hard to release the game in all major markets simultaneously. Right now we can’t give a specific date, but it should happen really soon as we are finishing up with some formalities.
The box art for the game was also just recently unveiled so you can take a look at it below.
