How about... NONE??

Get a Sony FS5 instead. 
 
I think in his situation then he is in a perfect place to jump ship to something better, as with merely a 60D & SL1 he is hardly heavily locked into the Canon ecosystem right now.

Awesome!! We're going to see affordable cine zooms soon from Samyang?? I'd love to have a Rokinon version of the Fujinon 19-90mm T2.9 but at a price I could actually afford!!
 
 

You could get the G80/85/81 that in a couple of ways sets it apart from the G7 and GH4. You still feel you need more productive features... wait for the GH5. It's a few months away. Or... by then the GH4 will also have dropped price a bit more and people replacing theirs, so grab a GH4 then...

Of course, radiation fits zombies like a glove.

Agreed, if you want a cheap 4K action camera then go with the Yi 4K

I shot with the pocket for a while. I always thought I was steady but would need to warp stuff if shot handheld. Such a great camera though. 
If you ever get a chance, try the Sony F3. The size is huge compared to the pocket but the image is very similar oddly enough. The added weight, xlr, and nd does come in handy.

BMCC? You can pop the BMPCC speed booster on it for a 1.38x crop and an effective native ISO of 3200, which should be enough for most low-light situations; you'll get 2.5k, which will give you some of the wiggle room you're used to with the 4.6K; and the menus, color science, lens mount, and workflow will be identical between it and your UM46.

Otherwise, maybe a used F3. Nice low light performance, S35, internal NDs, 10-bit 444 output, decent color, beautiful highlight roll-off, great DR, and iirc it even takes the same batteries as your FS5. The biggest downside is that it's "only" 1080p, but other than that? Not much downside.

Yes. You pay for what you get. Possibly getting upscaled 4K from low-res too. There's decent alternatives to a GoPro that cost way less than a GoPro. But still if you want something that works well, you've got to pay up. Even within the cheaper China segment, like the 100$+ Xiaoyi/YI, SJCAM, GitUp, etc.

Yeah, that says a lot, doesn't it. Honestly, Albert Fast has been doing great stuff with the G7! And it's an cheap as fuck camera that doesn't overheat! He uploaded this a few days ago:
 

The lesson is - if the Sony model doesn't quite meet your requirements, wait a bit and they may find a way to add the features you want. With Canon, if the model doesn't meet your requirements, you might as well buy it, as you will have to wait 4 years for the next model, and it won't be much better.

I was excited to see a new 12-60mm lens as it could be the perfect run and gun lens (the MFT equivalent of a 24-120mm), but then I saw the f stop.....  f3.5-5.6! That sucks. Wanted *at least* constant f4

10bit and 4:2:2 would have been in nx1-mk2 for sure, if it ever existed.

Very likely a large portion of that low score is due to dumb FS7 owners buying and it expecting something totally different from it than what it is.

Sigma 18-35mm f1.8 with a focal reducer will cover a MFT sized area approximately. 
Not a good idea!
With a straight adapter it would be a good idea with a Sony a7R mk2, but not an a7S mk2.
 
What is your budget and purpose? As there are HEAPS of options for lenses!
Do you want to go mainly adapted or native mount lenses?

Personally if it was me I'd go for a mix, I could get together a nice little set at a very low cost:
You can pick these up second in Nikon F mount for cheap cheap:
Tokina 16-28mm f/2.8
Tokina 28-80 f/2.8
Tokina 80-200mm f/2.8

Then throw in one of the cheapest Sony FE mount lenses, which makes it quite a good value (unlike most Sony FE lenses):
Sony FE 50mm f/1.8

All in cost is not much at all, and you've got four nice lenses which cover a lot of uses.

Think the Nikon D750 with a Shure VP83F LensHopper might serve you well.

With a speedbooster you are not far away from full frame looks either. 

Not when the GH5 is about to come out with its superior specs. It makes perfect sense to get some more sales in while they can.  Its essentially the same camera as the 6300 with upgrades which explains how they managed it so quickly.  The added ibis makes people think twice about getting the G85 and GX85 too.  The price pushes it too close to full frame for my comfort though.

touchscreen and IBIS confirmed

24fps raw stills for 150 shots... so that opens up the possibility for around 6.25 second bursts of raw 6k video! Maybe someone crazy will make a video with it. It'd be a lot of work, but might be kind of a fun challenge. 

If it keeps to the launch price of the a6300, has IBIS, touchscreen, and no overheating, then this likely will be the camera for me in 2017. (throw in a headphone jack please as a sweetener)
I am however surprised at how fast the release cycle has been for the latest a6x00 series, I was truly expecting an a5100 successor to come along first. 

Indeed. http://www.43rumors.com/ft5-confirmed-via-trusted-sources-the-panasonic-gh5-has-5-axis-stabilization/#disqus_thread
Now let's see about the AF. If it as usable video AF then that's going to be a BEAST.

Headphone and Mic jack please

If you use a speedbooster then you'll lose all benefits in picking Canon for their AF.

For Canon DSRLs, 1080P exists only on paper
