Playstation 4, what happened?

Playstation 4 was released on 22nd of november 1 week ahead of Microsoft's Xbox One release. It took the market by storm. Stocks flew off the shells of every known dealer in the US. It also went way past ahead of its prequel, the Playstation 3 and the Xbox 360's sales from 22nd onwards. Although Xbox One release was also a huge deal especially for Microsoft but the Playstation 4 stole the spot light from it too. Recently Sony announced on CES 2014, that it is overtaking its competition (Xbox One) by 1.2 million consoles which is a pretty huge amount to consider. Until most recently a microsoft exec announced that Xbox One has finally taken over the Playstation 4 sales. This was kind of a shocker as these two announcements were only like 1 or 2 weeks apart. Why? What went wrong?

This is the question we can maybe know the answer of. Sony has not been able to keep up with the orders as mostly the Playstation stock is mostly finished. Pre-orders have been delayed to March. There were minor problem in the consoles from the initial stock with some people having a problem with the HDMI out. If Microsoft's claims hold weight, I think these are the reasons which backtracked the Playstation 4 and allowed Xbox One the market domination.
