There are third-party apps for conforming picture edit changes to a Pro Tools session. But there's a chance for Avid to give Media Composer and Pro Tools users a beneficial feature. Because both apps are from Avid, they could provide a proprietary conforming feature to ease and speed up the workflow between MC editors and PT artists.
Like Avid would value that a production crew uses Avid tools for the whole process.
MC already outputs sequence interchange formats like EDLs / XMLs / AAFs / MXFs. If Pro Tools could compare and align all video and audio clips to the changes out of the box, that would be a really welcome feature for post production staff.
