Well, if you look at Nissan - although it's legally a Japanese company... but it is basically owned by Renault (43%) - or perhaps it should be at least called it's under "Renault Group".
(Rather interesting story - that guy Ghosn and all. lol)
The Japanese law may forbid the Sony to be sold, but like Nissan, it could be merged - or like Vaio, the Playstation brand itself could be sold.
Sony's business structure wise - if you look at the Sony's CEO list, CEOs, other than the head of the company Yoshida himself - are all western dudes.
Rob Stringer (Sony Music), Anthony Vinciquerra (Sony Pictures), and Jim Ryan (SIE)
But is Sony still a Japanese company? Honestly, the line is blurring.
Even Hermen Hulst (Playstation studio) said in a
interview
“I will say that we are in some ways very much a Japanese company still. That’s our heritage. That’s still part of who we are. We love our Japanese games,”
And imagine how this
"In some ways" was interpreted among some folks... but you can't deny that it means "in some other ways" they are not a Japanese company, but a global company - which I do think is more correct, even though it is incorporated in Japan, traded in Tokyo stock exchange, etc - just like Nissan.
It is unlikely that Sony would be selling its lifeline at this point, however - but Sony being a Japanese company may be thing of the past, and only true in strictly legal sense, not in practical sense.
