I was hoping that the rumours of G17 using 1" sensor to be true. But somehow, they decided to skip G17 and made G7X and G5X or any other camera except for G17...Well it would be great if the g5x offers a big improvement in IQ and noise performance over the (now effectively discontinued?) G15 /G16 form factor point & shoots.
The way I see it the issue with the canon G cameras for UW photography has mostly been the compatibility with wet wideangle lenses, with the air dome solutions only offering the equivalent wideangle of the cameras lens on land, or specialty lenses like the inon zm80 forcing you to use smaller apertures for decent corner sharpness.
The last high end compact from canon to have a simple wet wideangle solution seems to be the s120 (unless you count the g7x with a dedicated wide port)
I agree that the g16 is a great choice in terms of features and value - right now I use a g15 and find the macro and closeup capabilities very impressive especially with strobes. But going wide is not easy with these cameras and iso of 400 and up results in a very steep nosedive in IQ.
So if some aspect of the physical proportions of the g5x lens, or the housings' ports developed for it, allows good WA with all those awesome dials and wheels I'd consider a major leap from the g15/16 line and worth the extra $$.
But as some point out this seems to be the lens from the g7x anyway so perhaps my hope for good WA compatibility will be wishful thinking.
The DOF benefits, close-focus and high magnification of the g15/16 cameras makes them excellent macro and close-up/portrait specialists which I'm frankly sad to see not being continued.

... If you were hoping for a G17 with 1" sensor, well that would be called a G7X, or if you want it with a hot shoe and EVF, well that is now a G5X. If you want an S120 with a 1" sensor, that is the G9X.
...and their G3X is a super zoom, which is useless underwater.
That's what I'm talking about. If they say they are changing the numberin system, most of the things just doesn't seems right... other than the 1" sensor.... most of the features are being traded off.Not sure its that simple. I guess the main question is: are any of these cameras are as well suited to UW use as their predecessors?
Outstanding issues as I see them are:
G9x - no front dial like S series + useless touch screen means it is unlikely to be good for manual shooting, zoom range impractically short for macro
G5x - short zoom range + large sensor means not naturally as good for macro as smaller sensor P&S w longer zoom range. Possible issues for true WA like g7x
G3x- N/A
G7x- housings which fully enable you to have both macro and wideangle require separate ports for each, so why not invest in ILC if you are going to spend that much $$?
Sorry to only highlight the negatives, I'm actually a canon powershot fan but every new G release seems to present big tradeoffs/impediments for UW use since the move from 1/1.7 in. Sensor compacts. Especially considering the whole advantage for taking a P&S underwater is meant to be the cost effectiveness and ability to do both WA and macro on a single dive.

Macro 5cm(G7X) vs 1cm(G16)Mr. Evans, I think you are being a bit too pessimistic. I think the answer to your first question is yes. All the reviews I have read agree the G7X is a step up from the G16 for underwater. Macro performance is quite similar if not better than the G16, and with an accessory macro lens, the G7X is very very good. True, with a regular port, you can only go to 28 mm equivalent, but that is not so bad. Nauticam does have a short port so that you can go wider with an accessory wet lens, but that is only if you want wider than 28 mm. You don't have to get the short port (and housings other than Nauticam don't have it), and the camera is still quite versatile.
Have a look at Alex Tattersall's review of the G7X, the photos to me look amazing! Review: Canon Powershot G7 X by Alex Tattersall :: Wetpixel.com
To address the other points you make:
G9X does have a front dial, although that is the only control dial.
G5X has the exact same sensor, lens and zoom range as the G7X, and can focus down to 5 cm, so already proven to have macro performance very similar or a better than G16 (despite larger sensor). It is the G9X that has the shorter zoom range, but this may actually be a good thing for underwater; 28-84mm equivalent to me seem perfect. Lens can focus down to 5 cm so should be fine for macro, while at the wide end, probably will be able to take a wet lens without the need for a shorter port. 84mm vs 100mm not a big deal to me, since quite often the best macro performance is not at full tele (as the minimum focus distance may increase when fully zoomed in).
So for me, I see the release of the G5X, G7X and G9X as positives for underwater compact shooters.
