Audio to Expression Release?

Upon hearing about how v71 will have Audio to Expression, sounds like it's gonna be the descendant of OVRLipsync, I wonder when we will have access to it through plugins. Will it be its own plugin? Will it come included in Meta SDK? I'm just looking forward to testing it. Oh and I hope it has options to either use the standard 52 Blendshapes as well as Meta's 63 Blendshapes and we can just choose which one we want.

When do you all think it will come out for Unreal?
