yes, all live dramas have gone by the wayside. People actually told me last year that they spent hours and hours before the 2014 Regional convention practising dramas. When convention time came, much to their surprise, all their practise was moot because they now use this technology to broadcast videos.
Wouldn't surprise me at all if they start using more and more GB members to give recorded videos at assemblies, in a way to make the R&F more awe-inspired or more fearful of the Borg.
