After the phantom 3 news it looks like all we need now to make a phantom 4 and the inspire redundant is 360° gimbal and retracting UC. A zoom function, preferably optical rather than digital and a recovery parachute would top it off nicely....
Their are a couple KickStarter projects working on this now . A monster like DJI will never toss in the towel .. There are always things such as object avoidance, follow-me, etc.
360 gimbal is only useful for a two man setup. One man setup, IOC is your 360 gimbal.
BTW, 4K res at 1,000fps would be about 1Gbps bitrate. You can get that now for a cool $120,000.
