Neither Sony nor Microsoft are Chinese companies so Coronavirus outbreak didn't affect them too much so far. However, their troubles may start soon as the planned releases for PlayStation 5 and Xbox Series X might get bumpy due to quarantined workers in China.
Consoles of the next generation are still nine or so months away but manufacturing issues might delay the day we get to enjoy the upgraded hardware. Namely, both companies are relying on Chinese production and the country emergency services are actively quarantining employees of some factories.
For example, Apple already is already in deep trouble as Foxconn has already taken measures against the virus spread. As you probably guessed, these measures include limiting workers' movement and efficiency which will likely cause the next iPhone's production schedule to be altered.
Closer to the console gaming area, due to the manufacturing problems in China, also caused by Coronavirus. On the topic of next-gen consoles, however, there is no direct confirmation that delays would happen but there are strong indications.
There is currently no confirmation or any indication directly from Microsoft or Sony so keep in mind that the fears of delay may or may not come to pass.
