The one thing that would stop a media composer from migrating to Studio One is the lack of ability to export a video with the project audio rendered into it.
We often have to send across videos with our music embedded into it or feedback from agencies, directors, studios etc
In Logic you are able to export a movie you are working on, and choose whether to replace the inherent audio - or add to it.
Without it, nobody is going to be migrating any time soon. Hopefully it's coming ??
