I think its perhaps to late, Go pro has had any incredible boom over the past few years and made Billionaire of the inventor, but all the big brands are getting in on it now, alongside the other guys that just made action cams, now we see product from Sony, JVC and Panasonic with their release just last month (although not sure that'll catch on being a two part design).
Most of the opposition is coming in at lower price points than Go pro and some better innovations like displays on the camera to review footage, GPS and image stabilisation although they all have their flaws, shouldn't take to much for one of these guys to get its design right with good mounting, good image sensor and battery life etc.
In fact your mention of apple is quite relevant. I think Gopro has slightly arrogant view point like Apple and it may very well be someone like Samsung actually in the action cam market also that pulls out something that kills gopro on spec at a better price point down the track and will dominate the market.
I think Gopros success has caught the attention of all the big guys now and only a matter of time till they get it right. I've held off upgrading my Hero 2 for something better as Hero 3 doesn't really quite meet everything I want.
edit: Saying all that, I think Gopro shares will do well, certainly over the next 12 months, with new camera likely on the horizon before the end of the year which will give them a boost for sure.
