Update, 8/23 2:35 p.m. EDT: Sony has now confirmed both the DualShock USB Adaptor and the launch of PlayStation Now for Windows PCs. That service will launch in European territories on Wednesday, August 24; a North American launch of the game-streaming service will come "soon after."

The DualShock USB Adaptor will work only with the DualShock 4 controller, as opposed to the PS3's DualShock 3, and will cost $25 when it launches in North America in "early September." (European users can expect their version to launch on September 15, but that version's price hasn't yet been announced.) Its compatibility with Windows games will come down to whether games support the DS4's specific features, including light-bar colorization and touch-pad compatibility.

Original report: PlayStation Now, Sony's two-year-old game-streaming service, will soon come to Windows PCs, if an incorrect image tag on a Sony blog post is meant to be believed.

Game-news sleuth Wario64 posted the discovery on Tuesday after mousing over an image promoting the upcoming PlayStation VR Worlds game. Upon doing so, a caption for something entirely different popped up: "PS Now on PC Announce Post by PlayStation Europe, on Flickr." Ars confirmed the caption was still live as of press time, though a peek at the blog post's metadata didn't point to any links to such a news post.

The news follows a report from French gaming news site Gamekult earlier in August that suggested PS Now would first be announced for Windows PCs in Europe on August 23, with American users getting a crack one week later. Amazon France may have also let the streaming cat out of the bag on Tuesday by launching a product page for a "DualShock USB adapter for PlayStation 4," which could be used to more easily connect the PS4's DualShock 4 controller to Windows PCs—though thanks to an empty product description, that's only speculation.

PlayStation Now currently allows gamers on PlayStation 4 consoles, PS Vita handhelds, and select smart TVs, to stream older PS3 games from a cloud service. Our testing has shown improved latency since its 2014 launch, and thanks to a broad game library, the offering is among the best in the nascent game-streaming industry—so long as you don't mind being stuck with years-old PS3 games.

We have asked Sony to confirm the legitimacy of the photo caption in question and will update this report with any response.
