It's PS4 vs Xbox One time again and it seems that the PS4 is winning because everyone has been buying a lot of PS4's that Sony can't keep up with demand while Xbox One consoles are not selling that great!

PlayStation 4 stock still isn't adequate, according to Sony Computer Entertainment CEO Andrew House, and won't meet demand in full for a few months yet.

"We're struggling to keep up with demand," House told the Wall Street Journal of the PS4 at GDC.

"Conservatively, as we get into the early summer months, we'll be closer to a full supply situation," he added.

Demand has been strongest in North America and Europe, the executive said, but sales are strong in all territories where the PS4 is available.

At last update, the PS4 led the Xbox One in cumulative global sales, with 6 million PS4 sales worldwide as of early March, while Microsoft hasn't said anything since announcing 3 million Xbox One sales in January.

According to the NPD, the PS4 has outsold the Xbox One in the US and the rest of the world to date. Analysts expect the PS4 to close out 2014 with a 3 million sales lead on the Xbox One.

According to the firm Wedbush,the PS4 sales by the end of 2014 will be at 12 million units, Xbox One at 9 million and Wii U at 3 million.

And according to their report the Wii U's weak projection comes from Nintendo's failure to tap into online multiplayer, while PS4 has been a, "phenomenal success right out of the gate."

Wedbush argues that Xbox One is falling behind its closest rival due largely to the console's high price point.
