Prior to the Xbox One reveal many thought Xbox Fusion would carry the namesake of Microsoft's next-gen console. The information came to light after a domain registration blog, Fusible, reported that Microsoft had registered several domain names related to Xbox Fusion. Speculation circulated that the Xbox 360's successor would be the Xbox Fusion. Microsoft also registered similar domain names under other popular contenders Xbox Durango and Xbox Infinity. Yet Fusion remained a popular choice to be the Xbox 360's successor among speculators. Primarily because Microsoft not only registered the domain name but also linked it directly into the Xbox homepage. Microsoft had so much of an invested interest in the keywords 'Xbox Fusion' it led many to believe it was their next-gen console. But we've known since the Xbox One reveal on May 21 that Fusion definitely isn't a next-gen console. So now we've ruled out what it isn't, what is Xbox Fusion? What if it was never meant to be a console but something else? Xbox Fusion could be something new entirely and surprise us all. Here are our three best theories as to Xbox Fusion's secret identity.
