The Xbox One Elite Wireless Controller launched yesterday, and mine arrived in the early afternoon by mail. It was not a review unit, I bought it at retail, but I intend to publish my thoughts on the device in the near future. I am currently thinking up tests and benchmarks to run it through. Be sure to look out for that. It will be told from the perspective of a PC gamer who does not own an Xbox One console, and who does not intend to get one.
I have been using it over the last two days, off and on, however. I must say, it is pretty solidly built from what I can tell. The thumb sticks rolls around with basically zero grinding sensation, and the D-Pad feels precise (although that will need to be actually tested). It does feel just a bit awkward for games that center on the D-Pad though, because my left thumb feels more natural somewhere between it, the left thumb stick, and the “view” (back) button. It is certainly better than a standard Xbox 360 gamepad for “16-bit” style games, but probably not a step-up from USB-based knock-off SNES controllers for enthusiasts who go for that sort of thing.
It's definitely the best offering that I've used for titles like Super Meat Boy, though… even as far back as Windows 98/XP era. Granted, I didn't dip too far into the niche companies.
So keep an eye out for our later review. It will probably be one of the few that exclusively focus on the PC, and was written by someone who could potentially see themselves buying one… because I did. A word of warning though — the controller's firmware still cannot be updated without an Xbox One console (although the Xbox Accessories app to customize it is available for free in the Windows Store). I've reached out to Xbox PR asking for any update on that situation, and the answer will probably be a big part of the review.
