Interesting from their
T&C's to a competition to win a GoPro Karma we can get a better idea of how much it will cost and when it will be released...
The one hundred (100) winners will be awarded one of the following items:
One (1) GoPro Karma drone and one (1) GoPro prize package.
One (1) GoPro Karma prize package that includes (1) GoPro Karma drone and an assortment of GoPro products
Drawing date On or before April 15, 2016
Award date All winners will be notified on or before December 31, 2016
Prize Package Value Approximate Retail Value (“ARV”) of a Prize Package: $2,000.00 USD
Looking at that I'd say that the Karma will be released late 2016 and presumably they're going for Oct/Nov with steady supplies around January 2017 (similar to what DJI did with the Inspire)
It also looks like it will priced above the Phantom 3 Pro and 3DR Solo at what seems like $1,500 USD (assuming the price comes with a $500 USD GoPro)
Obviously this is just speculation for now and we will all know soon enough.
I'm just hoping they come out with a GoPro 5 without the fisheye as an option, if they were to release a Karma video without fisheye that would give away their next camera before its ready.
