Ok, just a tiny tiny rumour GoPro have been looking at smartphone camera tech, they have some partners in that area like Foxconn. http://money.cnn.com/2012/12/20/technology/enterprise/foxconn-gopro/

current HD3 Blk sensor is a Sony, this could also change.

I hope not to BM sensor supplier...

@Rambo

Where do you mention the ambarells next 4k chip and its use in the gopro?

I just come across the link because I like RC flying, I'm not sure of its veracity. For me the high frame rate would be great to be able to capture the energy and collisions in indoor flying. I reckon the specs are about right but the suggested release date is a bit optimistic.

...apparently this is the source of spec-ulation. He gives no sources so me thinks he is making the same assumption of everyone else , that since ambarella made the current sensor, they'll make the next one as well. I hope it's true but so far I think it's just guessing.

I'd add a guess...if this is true, the price will go up at least 50%, maybe double.

GoPro really does a good job of hiding their upcoming releases. I am not sure that hiding this is a good thing though. Nobody could duplicate what they had in the GoPro 3 even after 1 year. I would think that the publicity and hype would be worth more than tipping your hand a little bit?

If you are sitting with a Royal Flush you don't care what everyone else has. You just go all in and let everyone else squirm over their decision on what to do next.

Its still under wraps @peternap, I've heard nothing definite other than hints from a few insiders. Assuming the Ambarella Chip specs will be the new GoPro specs is just wishful thinking like I said a few posts up. The duel lens is something confirmed they have been playing around with as well as near field technology. The ability to easily share is high on GoPros list, it drives their sales.

@vitaliy_kiselev, yep agree, the HD4 will most likely go 4k 30fps and will need a hardware update to do that, whether it uses the above Ambaralla is as yet unknown.

There are very strong "rumours" of a duel lens single camera body Gopro addition to the lineup, not only to address the 3D sync issues but to also It could allow you to shoot in a couple different modes at once, so 4k30 on one side and 720p240 on the other and in a different FOV also. This sort of thing would be quite handy for many people that arent into 3d but give you more options in your edits.

The HD3 Black "PLUS" model will be introduced before moving onto the HD4, should be within a month.

Yep, those Ambrella Chip Specs where released back in Jan 2013, no evidence yet Gopro will use that.

Battery life is the biggest Achilles heel. Hope they address that.

These specs for the chip weren't leaked , they were announced and have been out for a while. And there's no "leak" that says gopro will use that chip, or use all of it's resources. Pure spec-ulation.
