I agree on this too. On the 4k deal and “very few people” have the TV for it…think back to the old days of video when full HD was new. I think a lot of people may have said that same thing. Now, it would be nice to have that full HD video from 5-10 years ago vs the SD. When i doubt, that 4k can’t hurt.
However, there are MANY things of the RX10 I greatly prefer. Some of them include: f/2.8 all the way, exp comp dial (I hate cameras that don’t have this), threaded shutter button (so I can use my soft releases), step-less aperture for video, aperture ring like a camera should have IMO, audio monitoring….those are the big ones for me.
Then again, Panny has advantages too. I’m NOT a fanboy of either…I’m more of Fuji guy. I have the RX10 and have owned a Panny GF1/GH1 and still have my LX5.
They are both great for what they are. Neither is a slam dunk vs the other. They will both appeal to different users. For me, right now, the RX10 is it for the above mentioned.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
