It has the same size sensor as the AX100 but technically a different sensor with a built-in LSI to do high-speed readout on the sensor. If you shoot a lot of fast moving subjects or your style of shooting requires a lot of movement of the camera you'd be better off with the new AX700 as I'm sure rolling shutter skew, a weakness of the AX100 at 4K but not so much at 1080p, will be less. The RX100V which has the same new sensor has already demonstrated this.
But if you shoot plenty of fast action you have to decide between 4K/60p on the new Canon and up to about 240p but only at 1080p with almost no resolution loss on the new Sony.
I currently own the AX100 and have been generally pleased with it. I am also disappointed that the new AX700 is limited to 30fps in 4K. The stacked sensor with double the read out speed should minimize the rolling shutter effect which is quite high on my AX100. One thing that should be mentioned when comparing the GX10 to the AX700 is that the Canon only has 8.29 megapixels arranged in a bayer pattern so you will not get anywhere near true 3840x2160 resolution. The Sony, on the other hand uses full pixel readout and oversamples the 4K by over 1.7 times (using all 14.2 megapixels) so when the video is "downsampled" to 4K you get true 4K resolution or at least as far as 4:2:0 will allow. Slashcam.de (https://www.slashcam.de/4K-Kamera-Vergleich.html) has res charts of many of the popular 4K cameras and the venerable Sony AX100 has one of the best results in both Chroma and Luma bandwidth. I played with the AX33 briefly before buying the AX100 but found the noise and resolution severely lacking in anything less than bright lighting but the BOSS stabilization was amazing.
I've never had a problem with rolling shutter on the AX100, I keep the cameras stable and don't do whip pans anyhow so not really an issue. I do agree on the 14.2 mp sensor and also the AX33/53 were only 1/2" type sensors compared to the 1" type (really only .6"). You don't want anything smaller than the 1" type sensor for 4K.
Stabilization appears to be hybrid, optical plus digital. I would say no 10 bit, that would be for professional line. Only one in that price range is the GH5. HDR, no not listed as you noticed so I would say that's not a feature like it is on the AX700. AX700 is a little lighter than the GX10. I would say the deciding factor is if you need/want UHD at 60p, otherwise save a few bucks and get the AX700 or go with the GH5, or wait.
1)the 'USB connect setting' with selection 'auto', mass storage' 'MTP' is not longer in ax700. I miss the date folder ax100 automatically create when transferring to computer
2)ax100 allow to the use of battery pack in unit battery became drain. ax700 require ac adapter if unit battery become drain.
3) menu system of ax700 is totally different from that of ax100. and no more LCD touchscreen on ax700. (note: cx700, cx760, ax53, pj760 ax100 all have same menu and touchscreen menu)
pro n cons
1) ax700 now allows time stamp on video. problem is default for time stamp is set to 'ON' . I wasted all my video shot yesterday. can it all have 'time stamp'.

Ended up buying the AX700 last month for a really good price. Have been playing with it since. Here's what I really like about it compared to my AX100:
Dual SD slots.
Fantastic auto focus
Fast RS sensor
Lots of Picture Profiles
Many more adjustments possible - too many to mention but the big one is the ability to adjust SHARPNESS. The ringing on the AX100 was a problem at times, particularly in outdoor scenes with finely detailed tree branches against a blue sky.
I've done some resolution tests and the sharpness is about the same as the AX100 (which is one of the sharpest 4K camcorders available)
I find the noise levels very good, especially compared to the many many camcorders I've owned over the years. I think the fact that the noise is much more finely detailed in 4K recordings (which is basically all I do) makes it much less intrusive.
I hummed and hawed for a good year about buying this unit as it did not have 4K 60fps, HEVC encoding, 4:2:2 capability, or true HDR.
To get HDR experience I found I had to use the simulated mode on my LG C7. It would not trigger automatically no matter what I did (which actually makes sense when you think about it)
Still, there are enough improvements that I don't regret the move. I got a good price for my old AX100 so it was a relatively cheap upgrade.
Resurrecting an oldie, but I missed a holiday deal on the GX10. I still want to go 4K. I'm also looking at the AX-700. I currently have a Vixia HF G30. I had a Sony prior to that. I like the fact that the Sony records in log. I like the fact that the Canon does 4K60. The Internet says the GX10's picture is soft compared to the Sony. Hard to tell from Web videos. Anybody have any real-world observations?
Of those who have cameras that can record in log, how often do you use it? Is it worth the time color grading in post? Lastly, has anybody tried Canon's Wide DR? (Is it close enough.)
