I don't think you will see a iMac Pro. Apple aims at the mass market, everything else is just clutter in their way. I expect apple to release a new macbook pro, which will be fancy redesign with "hip" features for the casual market (nothing that will matter much for professionals) iMac will just get a effortless GPU upgrade (if they wouldn't do that, they would be beyond lazy) The Mac Pro most likely wont be upgraded, maybe its discontinued and will die out like the Thunderbolt Display (thats what I think). ..Something I'm sure Apple has wanted for a long time, but only now have the "courage" (phun intended) to go through with, without the fear of it affecting their device sales. ...IF they upgrade the Mac Pro in the future, it will be as soldered design as the current and only upgrading the internals to stay remotely in the game. But, then expect that machine to be their current for the next 4-5 years before they bother upgrading or kill it entirely. Letting a company like Apple dictate when I should get a new computer (apparently never) and what internals I can choose from (basically controlled by their own sugarcoated deals with vendors like AMD) no way!...Ive happily switched and I'm never going to solely stick with one brand ever again. I miss the ability to send SMS from OSX, thats the ONLY thing I miss. Apart from that I got so much more, and a machine I can finetune and upgrade every year as I see fit and so many great softwares (and games) to choose from. This is a good time for every professional, that are not completely tied to OSX to leave, IMO. Ofc, some are dependent on OSX, ProRes codecs, FCPX and such, and I pity them for that. Apple should let windows use ProRes and program FCPX to WIndows, continue to support Quicktime on PC and let people have a choice. Because these are not good enough reasons over time to just stick with apple, and it just proves you never know when you can trust apple or they will just leave you in the gutter. Happily everyone have a certain amount of patience and at a point people will find other solutions. Soon ProRes and Quicktime will be replaced with other more open source softwares that TV companies and such can rely on. Apple is doing the same to customers that Steve Jobs badgered Adobe for with Flash a few years back, and we all see how well it went with Flash....slow death.
And I hope this will at some point sting hard for Apple, when their iDevices are loosing the cool factor and hysteria and Apples ecosystem is falling apart - no one can stay on top forever - And Apple with their arrogance deserves to be whipped off the throne.
Is that good enough badger for you?
