Nintendo fans have been asking, will the Switch be region free? Currently, we have no concrete answers from Nintendo. To start, the Switch is built on portability. We are assuming Nintendo knows that the Switch will become very popular on overseas flights, as demonstrated in the original teaser trailer. That alone suggests region-free support.
In addition to my thoughts, Laura Kate Dale, writer for Polygon and The Guardian, has confirmed on Twitter that she hears that the Switch will be region free. Other news outlets have also confirmed the same.
