I think this will be their big push into your 'iHome'; a major change in focus for the device and the reason it has taken soooooo long to develop.
My prediction:
New mini - much smaller form factor, black anodised aluminium, PCIe SSD, no internal 2.5" - but plenty of expansion ports for extra storage space and 4K+ video out. Intel Core M + A8(X?) processors.
This thing will be the 'always on' device, will have Siri, manage your home and is the bridge between all your current OS X, iOS devices and future connected light bulbs, thermostats, fridges, garage doors etc.
Starting at $999.
It will sport a new form factor, and it will adopt SSD's - It will definitely
NOT be a crossover device, and
NOT support
TWO CPU architectures - it would have to have two completely separate systems, two sets of all components.
Why do some of you think this will be the device to "merge iOS & OSX"??? Besides being not the way Apple is going to tackle this two OS dilemma, the Mac mini doesn't even have a screen, how can it have anything to do with iOS?? Would you have to go out and buy touch screen monitors for it? Apple release a new API for iOS devices to serve as its external monitor and it runs headless?
No no no, this will have Haswell's newest revision processors on it. It is the way the mini has always been treated as a product. The only way it will have an ARM processor is if it is released alongside the rumoured 12" rMBA,
IF that is going ARM already, then they could possibly have two Mac models running OSX ARM instead of just introducing one. If that occurred though, I would expect them to have an entire event dedicated to the new "magical Apple desktop architecture."
Much more likely, and it makes way more sense, they would do such an event and simultaneously release new models of EVERY Mac (except possibly the Mac Pro) on the ARM platform. This would show they are all in, and going to back the platform long term. I mean if they release one model, as a consumer I would be afraid they would abandon it if it isn't a big seller, and I would be left out in the cold. That would be the biggest barrier for most consumers on a one model release. Are developers on board? Will this be supported for 5-6 years even if it is the only model in the line-up to ever go ARM?
On the other hand, They would have to be developing 3-4 different levels of CPU/GPU packages though, unless they really intend to simplify it by having one level for the MBA & mini, one level for the MBP & 21" iMac, and one level for the 27" iMac. Even then, to release that all simultaneously would be a massive feat, even though we are not talking anything like the volumes of sales that we are for the iDevices. At under 20 million units in total Mac sales annually, this actually speaks against having many different packages for the different models, due to economies of scale, so I think they would stick to a maximum of 3.
Back on topic though, loving my 2010 Mac mini, which I have given 16GB of RAM and a 256GB SSD this past year. It is a new machine. 6TB of RAID 10 external storage for the media and photos libraries, and it is a home server dream. Really waiting on a new one though to get TB and USB3 connectivity. Don't care what architecture it runs on, x86 or ARM, just as long as it is fast enough so that I don't notice that it isn't.
