The AS10/15 looks good but your comments on the inability to deal with complex screen shots are holding me back a bit. I think I will hold out till Jan when the rush is over for
GoPro 3 black and there are more comparisons available. It also gives a bit of time for any undiscovered problems on any of the camera's to emerge.
The current reviews on the GoPro 3 black are very good on image clarity. It looks like a very good package.
The low light performance of the Sony is excellent and is far superior to the GoPro black, I think due being back illuminated.
This video made my mind up to buy the Sony, as it shows it's superior low light performance.

Both camera's have their own advantages and disadvantages, I have a GoPro Hero 2 and was going to buy the GoPro 3 black but I feel the price is too much for a camera not very good in low light conditions, which is important this time of year.
In my opinion the principle advantages of the Sony over the Hero 3 black are,
1) Excellent low light performance,
2) Battery life, over 2hrs 10mins whereas the Hero 3 is reported to last just 1hr 17mins(both 1080p),
3) File size, a 32gb card is enough for over 4 hours with the Sony but my protuned GoPro Hero 2 uses up the 32gb card in less than 2 hours(both 1080p),
4) You can buy cheap OEM batteries and chargers for the Sony.
5) Price, for the current RRP of the Hero 3 Black you can buy 3 Sony AS10's.
I maybe be tempted next spring just because I find the 2.7k setting interesting but that depends if the price comes down and if GoPro sort out the bugs, something common with GoPro and also something they are not great at fixing in a speedy manor.
