Originally posted by Adam WG-series has been at a technological standstill since the WG-3 came out in 2013. Perhaps consumers really don't care for features or image quality? I mean, who needs 4K video underwater?
That said it would be nice to get some updated, faster hardware- sub-par performance can really hurt the brand image, and there's definitely still potential with the WG line.
The Oympus version is highly rated. I literally just researched this for my brother, and it consistently came up number one in reviews for rugged travel cameras. In the end he purchased the Olympus TG-4 variant, after going to check out the Ricoh version, and finding no one had it in stock. By contrast the Olympus was on offer in lots of places. The need's not huge in the market, but it's a section that does sell, albeit in small numbers overall.
As an aside, what does being under water have to do with recording resolution? If one wants the best video quality possible to record their travel experiences, then a 4K capability could appeal. 4K is simply a resolution, like 720 or 1080. It will become the standard very quickly, and Pentax will need to react. Pentax can't keep throwing out its standard video package forever, DSLRs included, bearing in mind directly your comments above about sub par offerings being damaging to a brand.
