It looks as though Microsoft could be planning to announce an updated Xbox One controller at E3 2015.
In a document uploaded to the official Microsoft support site and first spotted by Eurogamer, Microsoft details a new addition to the Xbox One controller: a 3.5mm headphone jack. This would make the Xbox One controller more compatible with various gaming headsets that otherwise currently require the use of a separate dongle.
The listing on the support site has since been removed, but a cached version of the page still exists, and the image can be found here. We can only assume that Microsoft is going to announce the new controller at E3 2015. Hopefully, they’ll have some sort of trade-in program, because I’m not about to spend another $50 on a new Xbox One controller.
Microsoft has said in recent weeks that their E3 event is going to focus on upcoming Xbox One games, but I wouldn’t be surprised if they slipped in this little announcement.
