General Conference 2016 only 720P

Does anyone know why the YouTube clips from Conference this Spring Session 2016 have been limited to only 720P? Conferences from last year that were posted are available in 1080P. Last weeks Relief Society broadcast that was uploaded to YouTube is also limited to only 720P

I think they work as quickly as they can to get everything up at 720p. It is a good enough quality for most uses. Once everything is available online after the conference, they will add the 1080p files for those who have the bandwidth to download and use them.
