Looks like GoPro have launched a new camera shipping today.
The cynical part of me assumes that they couldn't fix the problems with the previous model so they've released new hardware.
Other than that it seems to follow the usual thread of improvements:
Smaller/lighter/sharper, although I guess the 30% battery life improvement is significant.
- 20% smaller and lighter than Hero 3
- High resolution, high-frame rate 1440p48, 1080p60, 960p100 and 720p120 video modes. 4Kp15 and 2.7Kp30 enable ultra high-resolution, cinema quality capture.
- 12MP stills at up to 30fps, plus time lapse and photo burst modes
- New Superview wide mode
- New auto low light mode
- New sharper lens
- Improved audio and wind noise reduction
- 30% longer battery life
- faster (up to 4x) wifi connection to the GoPro app
- Social media sharing
