If Apple are having it as a surprise feature they are not going to show it on the images are they, Touch ID would be on a separate accessory anyway it’s not like it would have to come with the iMac Pro. Face ID will not happen on the iMac this year.
Well, the most likely development for the iMac is Face ID, not Touch ID - obviously much easier to stick a face ID camera in a future iMac than implement secure TouchID in an external wireless keyboard! Also, I'm guessing that the new, extended Magic Keyboard released at WWDC was partly developed with the iMac Pro market in mind - I don't think that would have happened if a new Touch ID keyboard was in the works.
However, I'd see Face ID as more likely for a future "consumer" iMac - doesn't seem like a big draw for iMac Pro target users.
Meanwhile, no I wouldn't rule out an October/November event to launch the iMac Pro "properly" - WWDC was only really a preview, with what might easily have been a mockup on "hands-off" display. Plus, I'm sure that they're itching for an excuse to use the shiny new Steve Jobs Theatre for something other than the staff non-denominational-winter-festival production of
Aladdin...
First off, they've announced they WILL update the Mac Pro.
It would be great to think an October event would include an update on the Mac Pro, which might show that Apple had got it into their thick heads that serious commercial users need some sort of roadmap for their long term plans - but my guess is that we'll see a repeat of the iMac Pro schedule for that - unveiled at WWDC 2018, orders in December 2018, production delays into 2019
🙂
However, its not impossible that the current Mac Pro will get dropped before that (all depends on the stock levels).
Second, the much rumored discontinuation of the mini would have absolutely zero to do with the launch of the iMac Pro.
I think
@MacsRgr8's point was that the launch of any new product is a good opportunity to "bury bad news" and for old products to quietly disappear when the store is updated... If there
were any more positive Mac Mini developments (not holding breath) then they'd be a better fit at an iMac Pro launch than the September phones'n'watchstraps event.
