I love small drones. I don't fly large ones anymore, just too complicated, and regulations will make it impossible in the near future anyway. So I think you are in a cool market nowadays.
But while I love new drones I don't like vaporware or drone perks. Too many fails in this area, and for those that actually delivered (always late) the number of happy backers seems to be slim. Not saying this will happen with your drone but I'm just not a fan of this approach.
Gimbals in small drones? Small drones crash. I crashed my Tellos literally hundreds of times, and not one of them is dead or needed repair from a crash. I can't see how your drone could survive this abuse. A fisheye like the Bebop has with a better lens may be a solution but no gimbal.
The video quality of the microdrone looks very good - if it is unedited straight from a real microdrone 4.0 and not a fake. I'm not saying its fake, but you obviously played tricks on the Inspire part of the comparison video, so hard to believe you did not do so for the MD4.0 part.
Your comment under this YT video made me ROFL

Sorry, just want to clarify, the footage was provided by Duncan which was shot on Inspire (I agree it could also could have been compared with a Spark, Mavic, or Phantom for the purpose of this project), the resolution of both clips is 1080p so we can make a like for like comparison (check out the 4K original on his channel to see the full capabilities that Drone has). Hope people like it, I really wanted to show what can be achieved with a super low budget Drone 
Following this argument I can downscale the Inspire's videos to 640x480 VGA and compare it with a $20 drone like Eachine E57. Calling this "like for like" is ridiculous.
Also you are mistaken if you think $200 is super low budget.
Tello is low budget @$79 when its on sale but $200 for a "
Tello with Gimbal" is not. People just expect more from a $200 drone these days. MD4.0 is just not ticking enough bullets.
Your only option would be to build an open SDK and create an enthusiastic following, like the Parrot drones have.
I already mentioned a couple of other points in my previous post. Overall a nice drone on paper, but we will see what Micro Drone 4.0 is once its been delivered and tested.
