Around the Internet, various people and publications are reporting issues with the Nintendo Switch's Joy-Con controller. More specifically, the left controller has been seen as faulty with input lag and sync issues making it almost unusable.

Polygon, Giant Bomb, IGNand Kotaku are all reporting that the longer they play Breath of the Wild, the worse the synchronization issues become.

Nintendo has not yet issued a statement on these claims, but it appears that press members who got ahold of the console early are all experiencing the problem. If the Joy-Con controllers, one of the company's leading marketing points for the console, were to wind up busted… well, that's one of the last things that the company needs at this important juncture.

Keep an eye out for more information.

No need to panic just yet, but it's something to watch if you're lining up for a day-1 purchase.
