As far as I know, a precise date was not revealed. Microsoft did narrow it down to “the coming weeks”, so take that for what you like. One positive note is that it seems that Microsoft will push out the update much like they do with Windows PC updates, and push the updates directly to devices instead of going through carriers. This is a nice improvement over the Android model, which has so many potential choke points for updates, that it often means some devices never receive updates at all. I'm not a Windows Phone convert, but I have to give Microsoft some credit for this update model.
