With just 18 days of availability under its belt, the Xbox One has already sold two million consoles. The next generation sales battle is heating up.

Since so many Xbox One consoles have already found their way into homes, it's no wonder gamers have spent 83 million hours in games, TV, and apps on Xbox One since the system launched.

“We continue to be humbled and overwhelmed by the positive response from our fans. We are thrilled to see sales of Xbox One on a record-setting pace, with over 2 million Xbox One consoles in homes around the world," said Yusuf Mehdi, corporate vice president of strategy and marketing, on Xbox Wire. Demand is exceeding supply in our 13 launch markets and Xbox One is sold out at most retailers.  We’re also particularly excited to see consumers engaging in a wide range of games and entertainment experiences on the platform, with more than 1 million paid transactions* on Xbox Live to date."

Both Microsoft and Sony can now brag about multimillion sales launches. With Sony also boasting about its two million PlayStation 4s sold, the race to three million is on. Will either hit the mark before the end of 2013? Who cares? That both systems are selling so well is great for gamers, regardless of which system they've bought. Now if only the Wii U could step up its sales game.
