250 and 300 2strokes Fuel Injected

There's been a few rumours on the interwebs that the 250 and 300 2strokes will be fuel injected from 2018, to meet the Euro4 emission standards.  Supposedly KTM will be making the official announcement in June '17.  Two of these were tested on the Roof apparently.  Anyone know if there's any truth to this?
