And we are off to the Next Xbox races. Microsoft’s Major Nelson posted a countdown clock to E3 on Wednesday, sparking immediate speculation that Xbox’s next console edition is close. After dropping off the radar during the launches of Windows 8 and Windows Phone 8, the Xbox franchise is likely coming back onto the scene in a meaningful way: it’s time to retire the Xbox 360. The device, launched in 2005, has sold more than 70 million units. Now more than 7 years old, the console is all but a geriatric technological hangover from a different period. That said, the device continues to sell well. Making the reference all the more explicit, Nelson included a link to E3 in the post. The only text provided was “And it’s on…” Naturally, keep your hat on, Microsoft could be up to something else.
