If the latest reports are to be believed, GoPro is preparing to launch its latest waterproof sports adventure camera, Hero 4, sometime in mid-October 2014. According to Jim Duffy, an analyst with Stifel, the launch of the GoPro Hero 4 will be the biggest action camera event to date. A report by ValueWalk.com said that the research firm is of the view that the latest camera from GoPro will be priced at $499 – a significant increase from the price of Hero 3+ Black, which sells for $399. However, the San Mateo-based manufacturing company has yet to confirm the release date of GoPro Hero 4.
