Is Sony responsible for the PS4's great sales, or are Nintendo/Microsoft?

I think its Nintendo and MS made the ps4 a success... Basically what e3 2013 was a "Do Not fuck up" e3... And what I mean by that is, Microsoft basically went to e3 and said, we fucked up, Sony went there and didn't do anything impressive and Nintendo was a no show so between the 3, the company that fucked up the least was Sony and therefore basically won 2014...
