This is just a bad prediction. Not because i dont think Sony will bounce back, because I think they will. It is bad because there are so many other tech companies that have been even worse off than sony and have managed to bounce back .
I mean, even fellow console maker nintendo had a much bigger comeback this generation than sony is even capable of. OP should modify so that it will actually make sense. I dont think there is a tech company out there that is anywhere close to having a comeback similar to apples. Apples comeback is the greatest of all time, sony would have to be dead in the water and then suddenly rebound to be dominant in every market to have that kimd of comeback.
