Its more tied to the fact that the competitors are floundering, the Xbox One reveal was a mess, they flip-flopped on some of their policies, they are selling a more expensive console that has weaker performance, their focus is all over the place, they are forcing Kinect on people, their head honcho for the Xbox division just left mere months before Xbox One is released. The Wii U is...the Wii U, nothing else needs to be said how that console is doing, we have come to a period where people are hoping it at least does GameCube levels, that says it all.
Too much uncertainty regarding both of those products and companies, so that just leaves the PS4 standing there.
I am not committed to any of the consoles yet, nor am i buying any of them on launch, taking a wait-and-see approach but it is difficult to deny that the mind share is heavily favored for the PS4. They have had no major or even minor controversies, they have been saying all the right things since February 20th since that initial reveal.
Mind share can and likely will change eventually, but it is not a very controversial thing to say, right now 2nd july of 2013 that yes the PS4 looks like the best purchase for most people. It is the one console that actually has positive buzz going for it.
All this could change, the entire script could be flipped upside down, but so far, EDGE are probably right.
