This camera from Arri will finish off what was left of RED in Hollywood. The previous case for RED was the ability to fly their camera body on a variety of drones, jibs, and rigs. Now if a director is shooting on Alexas or Amiras (and who isn't in Hollywood?) and need to get a mobile shot or into a tight space they're going to grab the Mini, not the RED.
Further irony that this Arri announcement came on the heels of RED's Weapon camera upgrade announcement. I doubt that's a coincidence.
TIP: ShotOnWhat is a great resource if you're curious about what camera was used on a given movie.
