IGN's article provided an update with an official statement from Nintendo.
UPDATE: According to Nintendo, early Switch systems in the wild were stolen by employees of a distributor in the United States and illegally resold.
A Nintendo representative provided the following statement to IGN:
"Earlier this week, individuals claimed to prematurely purchase a small number of Nintendo Switch systems from an unspecified retailer. Nintendo has determined these units were stolen in an isolated incident by employees of a U.S. distributor, with one system being illegally resold. The individuals involved have been identified, terminated from their place of employment and are under investigation by local law enforcement authorities on criminal charges.
Nintendo Switch will launch worldwide on March 3, 2017, and we look forward to everyone being able to discover the wonders of the new system for themselves at that time."
