Microsoft latest leak is related to their Xbox One controller, getting a tweak from June 2015 and onwards (most likely we will hear more at the E3 event this year). The controller will get a 3.5-mm headphone jack. They had updated their Xbox support website with the new image below but quickly took it down.
They're also releasing a new wireless adapter for the Xbox One for PC so it's easy to use with the games you like. Apparently a few sources have mentioned that Phil Spencer head of Xbox announced it during a GDC presentation.
To be honest sounds like great news to me as you wont need a USB tether and for me preferably i liked to have the option to play my games from steam with a controller if I wanted to sit back and relax with no back aches. I was unable to get any more information regarding any other changes to the controller we will just have to wait and find out.
