I would love for Blackmagic Design to produce a camera for the Inspire 1. But their
Micro Cinema Camera is not what we are looking for: while it has a Micro Four Thirds lens mount, it does not have an MFT sensor. Its sensor is Super 16 sized, which is substantially smaller. That means less detail, more cropping, etc. It also does not support 4K.
So maybe some day, but I think DJI is who we need to rely on for the foreseeable future. And if they deliver with the X5R, all is forgiven.
Edit: this camera was announced in April 2015, and still isn't shipping. And its list price is $995.
