Tom's Hardware has published a review on the Xbox One
Eight years have passed since the Xbox 360 debuted and today's Xbox One introduction. That's a massive span between two generations of anything calling itself technology, never mind gaming consoles.The Xbox One Review: Unifying Your Living Room Experience
Let's put this into perspective. Call of Duty 2 was a launch title on November 22, 2005. In the time leading up to Call of Duty: Ghosts, there were 10 other additions to the franchise. Think back to the PC you were gaming on when Call of Duty 2 came out. Would it be able to run Call of Duty: Ghosts today? Probably not. Even though the CoD games aren't as taxing as Battlefield, the minimum CPU required for Ghosts is a Core 2 Duo E8200. That didn't even show up until 2008.
Consequently, this generation's consoles are pretty important to pay attention to; they'll probably be with us for the decade's remainder.
