I'm looking forward to the Karma and the GoPro5.
Of course the proof must be in the pudding before making any purchases, but it looks promising. If it lives up to the marketing, the Karma is basically the Solo 2.0. We can expect all the smart shot goodness of the Solo because they just hired the dev at 3DR who was doing all that work.
I think the timing will be perfect for a lot of us. Keep flying Solo for awhile and let GoPro work out the issues (and we know there will be issues). Once you are tired of your Solo, or you've gone through your last spare motor pod, then make the jump. By then the Karma will be stable and
@RichWest will have come up with some kind of crazy contraption to correct any jitters that remain in the gimbal.
Regarding multipoint cable cam, etc. the challenge isn't processing power. The calculations are not that difficult for modern silicon. What makes the Solo smart shots superior to the DJI / Litchi combination is the simple fact that Solo has a dedicated processor right on board sending instructions to the FC. On any current DJI platform (from the P4 up through the M600), the ground station software (Litchi or Autopilot) must constantly monitor and send new commands to the drone via the RC. This creates lag. The super great easing in and out on the Solo (a feature not lauded enough!) is basically impossible with lag and hasn't even been implemented (it definetly helps to have a strong direct LOS signal to the drone during smart shots). On the P4 specifically, cable cams are very hard to pull off because the barometer sucks and the damn thing won't consistently hit its mark (in terms of altitude), which borks your framing unless you plan for it. (I've been testing the hell out of all this on a P4, Inspire and even an m600. For now, Solo still best cable cam).
To whoever mentioned wanting a micro 4/3rds the DJI x5 raw is awesome!. The regular non-raw X5 absolutely sucks because it maxes out a 60megabits per second and the h.264 algorithm DJI uses is crap.
Back to the Karma...
Regarding that video at Squaw Valley, lets not overlook that thats at 9,000+ feet ASL. If they are getting 15+ minutes of flight time at 9,000+ feet, in strong winds, then that's bodes well for long flight times.
Karma has a cpu like solo for smart shots, it's got "boat mode", 2 point cable cam (assume more coming), built in (BRIGHT) 5 inch display, super compact, cool backpack, grip for ground shots, high altitude capability. Great stuff. Hope it all actually works.
