I made some quick calculations.
Canon LP-E6N battery has: 7.2V 1865 mAh 80gr, then power density is 0.168Wh/gr  
Fujifilm NP-W126 has: 7.2V 1200mAh 50gr, then power density is 0.173Wh/gr
Quite similar! Fuji even wins by 3%.

Hi,
 
Let's try an group the reviews for the new camera here...
 
As an X-photographer, I shot an X-100F for a few weeks and my review can be found here:

Always happy to answer questions here or on my blog.

I think anyone who upgraded to the X-T2 will think it's worth it ... they've spent the money already anyway
 
I think it's really up to you; do you want the camera enough to justify spending the money?

my sentiments exactly, I have X20, and  a number of Sonys, but I still like the charm of the fuji

Haven't tried the Ricoh GR but I played around with the Sony and it was just soulless. Fujis have that little something extra that just makes them a joy to shoot with.

I wonder also. Bought the RX100 III because I'm worried about the X30 sensor. But I just don't get a wow feeling with Sony which I have with my Fuji and Ricoh gear.

Go for the X70 : you won't regret it ... Sometimes I leave my XT-1 and X100T and Go with XQ1 , amazing little camera , still got the X20 .
 
But if you wait , X100F definitely , Good Luck my Friend . 

The FE 1.8/55 is one of the best resolving lenses ever made, while the A7R II is (specs-wise) the best mirrorless body ever made. So that's quite a match there. If I were you, I'd stick with that.
 
Besides the reasons milandro already pointed out (flange focal distance 18mm vs. 17.7 mm, aperture, autofocus), even if the fujinon lenses could be adapted to the sony mount, you probably would not want to, considering that the lens correction is done partially optical and partially via software.

This is one of the most important aspects concerning adaptive photography, together with the fact that lenses made for film were never made to perform well with a system, a digital sensor, which only performs at his best with rays as orthogonal as possible to the surface of the sensor. 
 
I use two lenses that aren’t communicating electrically and electronically ( by means of a chip) with the camera sensor and processor. The Samyanag 8mm f2.8 fish eye I ( the version II has an improved image circle that doesn’t seem to be a significant improvement on the APS-C) and the Samyang 12mm f2.
 
I have been wondering if it wouldn’t be possible to feed the camera with information, albeit general, on the adapted lens used. Originally that’s what I thought it happened when telling the camera which adapted lens is on the camera.
 
There’s a number of focal lengths pre-programmed and two ( why only two?) which one can modify. In reality modifying these only changes the exist data of the camera so that you can, afterwards, recognize the pictures and a program such as lightroom can order the picture under a lens directory.
 
It would be nice if the camera could be programmed to recognize lenses other than the Fuji or Zeiss.
 
Of course Fuji has no interest whatsoever in providing this feature which encourages people not to use Fuji lenses. However my take on this is that, with the exception of very few, most use adaptive photography as a creative extra, not as a total alternative.

actually in my the NL the secondhand x pro 1 bodies are more expensive that the price of new in Belgium!

X-Pro 1 is going for peanuts second hand nowayads. If you don't own a Fuji body yet, I'd consider picking one up just for fun and to have lying around the house. Those lenses are amazing. I would keep all of them for sure.

I don’t think that there is any such adapter to use a Fuji lens on a Sony A7RII.
 
There are multiple reasons why there isn’t one and there will never be one...
 
 
 
 
1)  The flange distance of Fuji is smaller than the one of Sony.
 
2) The aperture of fuji lenses is not working on the lens without it being attached to the camera, only lenses such as ones without any electrical contacts ( e.g. Samyang) have operating apertures 
 
furthermore, the focusing of many lenses of the system is also electric and won’t work without electric contacts.
 
Sell the Sony !
