Well, talking exclusively about wildlife photography, I think we have a great idea. More FPS will help capture peak action, and the continual march of more efficient computer processing and refinement of AI will result in better AF. But (1) the vast majority of wildlife shooting scenarios became child’s play for AF systems back in the D5 days, and (2) we’re going to need new storage technology to take advantage of those increased FPS. So, outside of BiF, the AF improvements will likely have a negligible effect. And even within BiF, I have serious doubt that there are standard deviations of improvement left to be gained beyond shooting small fast birds like swallows. Concerning the FPS, I don’t think that keeping up with 120 fps for more than 3 seconds is in our short term future, and probably not in our medium term future, either. If the buffer fills at 1-2 seconds, that’s not going to revolutionize wildlife photography. It’ll result in more options for peak action, if you can time it correctly, but it’s not a revolution. Now, that being said, I’m not one to bet against the market economy. So, suteetat is likely correct that we’ll get a new technology to take better advantage of the increased FPS, but I’m dubious that will happen over the next ~5 years.
So, again, very interesting technology, but I’m not optimistic that we’re on the doorstep of revolutionized wildlife photography.
With the exception of specialist flash imagery, the relevance of a global shutter to mainstream photographic genres probably is when FX sensors need radically fast scan rates. It is likely a global shutter will become more relevant - essential even - to engineers designing very fast sensors - must faster than 120 fps. Although, I haven't researched the scan rate(s) of the Movie cameras, eg RED or the new Atomos FX sensor with a global shutter (but not public), Note, that Nikon's industrial stacked sensor, announced early 2021, already achieves 1000 fps. So key elements of this Tech have been worked out.
Nonetheless, the mainstream applications of a Global Shutter have been and will continue to be video. What has relevant become relevant is the FX MILC companies are aggressively pushing into this market. This is no revolution for photography, as quite a few different movie cameras have refined GS tech, Sony included. FX is the latest recipient, and Nikon keeps stating video is a priority in the Z System, which suggests their global shutter is a given and probably soon
EDIT - one overview - https://www.cined.com/global-vs-rolling-shutter/
Fast storage is probably an important factor in enabling fast fps, particulalry FX RAW at 120 fps and faster. CFEXPress B (more so C format probably) - currently v4.0 - will also probably leverage higher frame rates, but ultimately may require a new image storage standard - in a few years.
Regardless, the ability to capture critical moments - at 60 fps - is no new revolution. Some years ago at least one of the Nikon 1 CX MILCs had Pre Capture, and a similar feature has been standard in some of the Fuji and Olympus MILCs for a few years - recording RAW images.
For FX ILCs, Nikon's Pre-Release Burst has become the keystone feature to capture precise action moments - first in the Nikon Z9 in FW 2.0 (April 2022) and latterly Z8 and Zf. Thanks to a high speed electronic-only shutter, both Z8 and Z9 deliver stunning captures at 120 fps, which confirms a global shutter is unnecessary. RAW has been missing in FX but we can have confidence it will soon be a standard format.
There are any number of examples of the stunning captures enabled with Pre Release. And there are any number of applications across sports, and even more in nature - think of how animals fly, leap, run, diver, hunt etc and some plant fruits release seeds explosively etc.....
