Is audio system rewrite delayed 'till summer ?

So, I was keeping my hopes up for audio system rewrite to be completed soon (I recall April was the last bar on Trello) and have spatialized audio available for Gear VR. Now I see the last bar on the card is “June” o.O

Epic devs, could you please let us know if spatialized sound and HRTF for Gear VR will be in UE4 by then ?
