Nothing at Sony will change until they remove Kaz as CEO. He has failed to reform the major money sink which is TVs and is selling the PC division two years too late, losing value in the process as well as wasting money that would have been better spent promoting their mobile offering.
On the plus side it reads like Sony are just bringing forwards the 30bn yen worth of extra losses from their PC sale that would have been counted for the next financial year into the current financial year so they can take advantage of certain tax gains by closing the sale early. That means they expect some kind of profit next year.
The bigger issue for them is the failure of Blu-ray to really take off. While today's write off is a bad one, it also, finally, closes the door on Sony ever recouping any of the money they lost selling the PS3 at below cost for 18 months because of Blu-ray. The initial estimates had the cost of a Blu-ray drive at $240 vs a DVD drive at $19. It wasn't until mid-2008 that the cost of the drive had fallen to manageable levels (around $40) and it took until 2009 to see the cost fall to DVD levels. That money is not going to be made back in disc manufacturing and royalties as Sony management said back in 2006. The market for physical media has waned, and in no small part from their own efforts. Looking at their 4K ecosystem, not a single mention of Blu-ray 4K was made at CES, the PS4 does not have HDMI 2.0 or a 4K compatible Blu-ray drive. The mentions of 4K content was all about streaming, either Netflix 4K, or their own media server with their own rental/streaming service. It took Samsung to even bring up Blu-ray 4K at CES.
Sony should be:
Smartphones/tablets
PlayStation/SEN
Home theatre excl. TVs
Cameras
Semi-conductors
Movies/music
Financial services
Real estate brokerage
They need to cut out their TV division and invest the money saved into semi-conductors and expanding their smartphone presence in the US. Sony should be a content company with a delivery business to all devices, while giving their own devices direct access.
The worst part for Sony is that their TVs are no longer particularly expensive, at least the same as Samsung, but the perception after so many years is of higher expense that a lot of people don't even consider them. That is never going to change, not without significant expense in marketing which would be better used for smartphones, PlayStation and cameras.
The basic issue is that Kaz is a weak leader. He did not make the tough decisions in 2012 when he was appointed CEO, and now it is too late in the day to really benefit from shuttering the TV division in terms of shareholder value. The money that Sony have invested and lost in TVs would have been better spent on their other divisions, hell, even buying back shares in the financial services company would have been a better use of the money. Kaz is the problem at Sony and they need to bring in an outsider, recruit an expert bean counter from Nomura as the next CEO to tear down the walls and get rid of the loss making divisions.
