sony have a lot of traction, they have the majority of the imaging chip market. Rxiv is going to be my next pocket camera, check it out. And will probably pick up a sigma dp3 Merrill on eBay, there is something wonderful about the detail it resolves.
Blackmagic is another cool company, they don't make chips but their FPGA based RAW video cameras rock and they put out more firmware updates for all of their cameras in a year that Sony etc do in 10 years.
I'm using an RX100m3 as my pocket camera right now (after half a year, I'm still rarely using the EVF though, so I guess I could've got an m2 instead and saved a few hundred) but I've been eyeing Black Magic's hardware for a while. That EF mount 4K Cinema Camera looks delicious, although right now still a little pricey.
