sony is a LOOOOOOONG way from declaring bankruptcy. To even suggest this means that we shouldn't even take what you are saying seriously or/and that you have no idea what you are talking about.
For sony to go bankrupt, they must first be in a position where not a single facet of their business s making any money. And that will have to happen for at least 4/5 years before its deemed as an option, and that option only exists after they have put themselves up for sale and no one bought them.
As it stand, they would first cut off every part of their business that is causing them to bleed money and focus only on the parts that turn a profit.. eg Playstation, Insurance, Cameras, Projectors, sony pictures. The would cut off everything else and go back to turning a profit.
There are just so many options for them that its really silly even making a thread like this.
