A potential prototype for the unreleased Xbox Elite Series 3 controller has appeared online, offering a glimpse at Microsoft's next-generation premium gamepad. The controller was reportedly purchased for $200 on OfferUp by a Reddit user who then shared details on the platform. Following the initial post, the user's account and the original thread were mysteriously removed, though images and some information remain available through other sources.

The controller shares a strong resemblance to previous leaks of the Elite Series 3, featuring a similar shape, trigger locks, rear paddle mounting, and battery bay. Notable new additions appear to include slightly larger face buttons and a small mono OLED display situated between the bumpers. This screen, as seen in leaked images, displays a Microsoft-shortened URL and a basic game.

Following the URLs shown on the display has led some to documents concerning the controller's functionality and its potential for cloud gaming connectivity, a feature seen on controllers from Amazon Luna and Google Stadia. Further details from the original poster indicate that the D-pad design is similar to the previous model, and the triggers can be set to a shorter, clickier option. The controller also features a "PROTOTYPE NOT FOR SALE" marking on its battery.

Included with the prototype is a slimmer travel case, a feature consistent with previous Elite controller generations. This suggests that development may be quite advanced, potentially indicating a release before the end of the year. However, details regarding the internal technology, such as the use of Hall effect or TMR sensors for the analog sticks to prevent drift, remain unconfirmed.

The user who posted the initial information described the controller as feeling "like a Xbox Series X controller but pro and more clicky." Currently, the prototype is reportedly non-functional on both Xbox and PC, with speculation that it might require a specific developer account to operate, assuming it is indeed a genuine product.
