writes "Microsoft Corp. said on Monday that sales of its new Xbox One game console topped three million at the end of last year after launching in November and selling one million consoles in less than a day. The third generation of the Xbox is competing head-to-head with Sony Corp's PlayStation 4, also launched in November. Sony said it had sold 2.1 million PS4s by the first week of December. It will not be clear which company is leading the console battle until Sony updates that figure. However, the Xbox One seems to be selling quite well despite numerous obstacles including being over 25% more expensive than the PS4, the always-on Internet requirement that was controversial and was rolled back, and being sold in only 13 countries compared to the 48 countries that the PS4 is selling in."
