According to a report from InsiraFicha, it looks like SteelSeries has a new gaming controller in the works dubbed the Nimbus+. This was discovered in the ANATEL system, which for those unfamiliar is basically Brazil’s equivalent to the FCC. The Nimbus+ seems to be a combination of several controllers from the company in the past.
One of which is the original Nimbus that was released for iOS devices back in 2015, but its design also appears to be very similar to SteelSeries’ Stratus gaming controller, but presumably the main difference would be that it has been designed with iOS devices in mind. The leaked manual also suggests that it will pair via Bluetooth 4.1 and will work with devices like the iPhone 6 or later.
There is no word on when the Nimbus+ will be announced, but as 9to5Mac points out, the Nimbus itself, which is sold on Apple’s website, has been listed as out of stock, suggesting that maybe a refresh could be on its way.
