My first thought was that this would be a real test of what happens to newer consoles where electronic downloads from a (closed) central source (DLC, patches, games) are no longer available.
But after reading the article and comments here, I'm not too worried about Sony vanishing quite yet.
I don't think Sony could "vanish", more like their valuation falls low enough that someone buys them up at a "steal" for the brand and patent / trademark portfolio if they get cheap enough.
