http://www.eurogamer.net/articles/d...y-cons-tested-are-there-really-de-sync-issuesUPDATE 2/3/17 4:00pm: The Nintendo Switch's day one system update has launched, and there are reports online that installing the patch with the Joy-Cons attached updates the firmware on the controllers, resolving the de-sync issues. Is this really the case? Unfortunately not. We've updated our console with controllers attached and re-run the battery of tests detailed below. In all cases, the range and consistency of the connection of each Joy-Con remains the same, and the left controller still has demonstrably weaker range than the right. Eurogamer has contacted Nintendo several times now concerning this issue, and we still await a reply.
