Actually no it isn't to a degree.
There is actual proof that work suffers when you strain the workers. They also have experience working on consoles since Witcher 2 when it was released on the 360.
Them and you blaming consoles is foolish.
The CEO was on a conference call and outright said they was under no pressure to release the game. This problem was caused by mismanagement and releasing a game too early. The game should have been delayed by a year at least and this video is proof of that.
Also to add the PC port isn't sunshine and roses ether, so them being happy with the PC port is fucken laughable. The game is lacking a ton of systems and is still buggy. Its just less buggy on PC than console.
Edit: To add if it wasn't for consoles you wouldn't have CP2077. Over half of the Witcher 3 sales came from console and MS gave them a big wad of cash for the platform advertisements/deals.
Everyone else this year seemed to release a game just fine. This video was just PR fluff and honestly they would have been better off to not release it.
