It's rare -- unprecedented, even -- that Engadget re-reviews the same product. But game consoles are a curious exception. Though the hardware stays the same, these machines receive myriad firmware updates, sometimes long after launch, that make them even more valuable. That's especially true of the Xbox One, whose interface became much, much easier to navigate after a major software update last year. With our coverage of the actual games still going strong, we thought it high time we revisit the devices themselves. As such, we'll be rewriting, re-scoring and even re-photographing our original write-ups of the Xbox One and PlayStation 4. (With news that the Wii U might not live past this year, an obituary might be more appropriate than a fresh review.)
