I am hoping for at the very least a tease around NAB, if there isn't any buzz by then, I think it's a safe bet that there wont be anything at WWDC. If I remember right, there was some talk around NAB in 2013, that some were able to try the new Pro's (albeit hidden in an enclosure without any real indication of the 6,1 figure). There is where Apple (read Phil) needs to focus that they are interested in keeping that demographic invested. I fear if not many will be jumping to other platforms-granted many already have. For Apple to approach 4 years with the same system and price (by WWDC it will be roughly 42 months), it would seem that it is the end of the line.
They are really pushing Thunderbolt 3 (and why shouldn't they), It would make the most sense to see all the product lines adopt the port within a sixth month span or so. The first and really only TB3 system is the new MacBook Pro, to be followed by the iMac (one would assume this spring February-May), and likely extend to the MacBook in the next update. I hesitate to speculate on any other system (MacBook Air, Mac mini, or Pro) because I tend to think they are end of the line- I still hope for at least the desktop lines, but the writing on the wall dictates otherwise.
Although Apple may likely be headed towards a Touch Bar keyboard, I think it is far more likely that a Touch ID would be built into the chin of the iMac, possibly right next the the rear power button, or underneath. They are working on their products working with redundancy in mind, perhaps they will count on their users having their iPhone and Watch within proximity enough to work as a "two factor" or "two-product" authentication system, they already do with Apple Watch unlock, and Apple Pay through Sierra.
Unfortunately the only thing I could really count on Apple releasing in the next sixth months will be the new seasonal vibrant spring Apple Watch bands.
; Most Pros will drop out & switch to Win10 Creative Update.
