Is this just breaking it off Sony, turning into a "new" company and then sell shares of that, or is it out right selling it off.

Spinoff, iirc, similar to Sony Financial Services.

Can someone explain to me what this means for Sony as a whole?

Then that's not so bad. But won't it devalued sonys normal stock?

Sony should do it.

This means that if Sony the electronics giant dies in a fiery inferno, it won't take Sony the lucrative content publisher with it.

So where does Playstation fall? Electronics or Entertainment?
Please say Entertainment.

I think Sony should stay with all the stuff they have right now, if they are planning on the long road.

Products and services I think. Definitely wouldn't be part of the business they'd be splitting off

I'm shocked there is enough board support that they are going this far.

Makes you worry for Kaz and his ability to push through his own agenda/reforms.
