Interesting to read MS have said they've sold "Over 3 million Xbox One consoles were sold to consumers in 13 countries before the end of 2013." which given the dire predictions of a flop is a pretty good start, particularly when you take into account the PR FUBARs earlier in the year. Given it's still in only 13 countries vs the PS4s 48 it bodes well for a well supported platform going forward although only time will tell if letting Sony get a head start in other countries was a huge mistake or not. Without doubt SP4 will have outsold XO globally as the incumbent, in fact it's pretty remarkable Xbox has managed to gain the market share it has in a relatively few years competing with a giant that completely dominated the industry. It was only a few years ago that any console was referred to as a "PlayStation" although that seems to have slipped a bit of late.
For XO users hopefully this leaves us in a good position, XO has sold enough to be taken seriously by publishers to ensure decent titles, but has left MS unable to sit back and relax so I'm hoping for some real proactive improvements and updates based on community and dev feedback for the XO from MS over the next 12 months as they try to win back some market share. Fingers crossed although there's always the slight worry of never underestimating the ability of a huge company to screw something up.
