kind of sad that Gopros drone prototype looks better then what 3DR considered good enough to launch, and better then the gimbal they had months to work on...
In a fast developing industry, any product that comes out months subsequent to another will most likely be better. I don't criticize my computer simply because newer models are better.
And let's be honest - all we have are a few video clips. The GoPro drone may indeed end up superior to the Solo... but it may not. Simply not enough information to cast judgement. The footage looks fantastic, but if it's simply using a Hero 4, the actual video quality should be identical. The claim of no stabilization isn't a nail in anything's coffin - just like how smartphone manufacturers show photos from their phones that rival DSLR quality, these are probably the 1 in a 1000 shots made by highly experienced, talented photographers. GoPro states explicitly that the video was from a prototype drone - there's no question that that prototype would have been set up, props and motors balanced to a far higher degree than what will eventually make it through mass production.
Sure, the Solo has a few minor annoyances, literally all products do, but the biggest features - the automation - works, and 3DR is standing behind their product. I could have chosen an Inspire 1, considered it for a long time. But I kept coming back to the fact that DJI's support seems to range between poor to non existent.
Lastly, I, and others, made what we thought was the best choice at the time of purchase. Nothing stands still, so even if the GoPro drone does come out (and let's be honest again, who knows when it will actually be released, "early 2016" is pretty vague and noncommittal), and is superior to the Solo in every way, well, those are the breaks. If we were to always wait for the superior product, we'd wait indefinitely.
