Microsoft just announced they have sold over 2 million Xbox One's within the past 18 days. The Xbox One is on sale in 13 markets worldwide.
Sony announced earlier this month that they sold 2.1 million units. They have just expanded to a total 32 markets and sold around 2.1 million consoles in the same period as the Xbox One sold their 2 million. The Xbox One came out one week after the PS4.
Therefore, all the fanboys for either console can be happy that both consoles are selling well and will likely continue to sell in similar quantities for the coming months. Who will win this generation? We won't find that out for years. So let's all just get along.
