when will there be a Wwise Plug-in for a future UE4 version?

I am wondering if there is an ETA or any idea when there will be a more simplistic way of using Wwise with UE4.10 or future build as a simple plug in instead of building an integrated build of ue4 with wwise in it? the Audio Kinetic website says its integrated with UE4 but its a bit misleading as its not easy to collaborated with other people as everyone needs to have a costume build of that integrated wwise engine and every time an new update comes out, we all have to rebuild the source code with that new update.

someone ask an ETA about a year ago, but any progress??
