Numbers. Got to love them. Especially big ones. Microsoft has got a big number for us today. The number is 70 million and it relates to the total Xbox 360 console sales to date. To recap: 70 million Xbox 360s have been sold since Microsoft launched the machine in November 2005. That's quite a big number.
Based on current available data, Microsoft’s big number puts Xbox 360 in second place in the console league table of sales, ahead of PlayStation 3 (63.9 million) but below Wii (96.5 million). Unless something completely mental happens (like we’re invaded by disagreeable extraterrestrials who demand all humans buy an Xbox 360 or else they'll disintegrate everyone with their advanced disintegration weapons), then Nintendo has already ‘won’ this console generation.
