I haven't heard anything about a special version, but I used and loved ZB for many years because it's so fast & simple. IB is a bloated piece of crap that is always "updating the library" for 30 minutes before you can use it or downloading & installing updates and asking you to connect your camera via USB. It makes DPP seem like the best application ever written
Yeah, I find waiting on IB too frustrating as well. I would prefer a wholesale integration of all three (ZB, IB, DPP) into a single Lightroom-like application. I would like to see a database used, as that greatly simplifies searches and almost anyone with Photoshop can use Bridge if they don't want a DB.
Why would I like this? I don't believe I can dispense with Photoshop at this time. And I think both amateurs and pros would appreciate a single application which facilitates reviewing, searching, lens corrections, and simple edits. For early amateurs, it might eliminate the need for further software. For advanced amateurs, it would streamline the Canon software ecosystem and make it more usable and attractive. I think those could push increases in market share, too.
I would also love an application which accepts plugins. Okay, maybe they won't be Photoshop/Lightroom plugins, but if a software writer could quickly modify those to work with the Canon platform, I'm sure at least a few of them would and it would open up opportunities for third parties to hook into the Canon software. I can see that generating excitement for Canon products. Can you imagine if Nik/Google suite apps were useable in your Canon software?
As I've noted before, I suspect that dropping support for older cameras was necessary (at least initially if not permanently) as part of the ZB move to 64-bit. I own an older camera, but I am still happy with this decision
by Canon because I can continue to use the older version of ZB if I choose. I generally don't choose to use the Canon software because it is too time consuming to wait for IB, and no individual application has enough features by itself. If Canon wants to invest time on the software, I think upgrading to a single, more fully featured platform is preferable to making newer software backward compatible with earlier cameras. From a business standpoint, I am not clear why Canon is offering three separate applications.
