So all we know it's coming out in the fall which as you know Is Sept-Dec.
Erm, Fall in Northern Hemisphere is actually just Sep/Oct/Nov. Dec/Jan/Feb (Winter), Mar/Apr/May (Spring), Jun/Jul/Aug (Summer).
I've had this debate on Wikipedia with idiots trying to edit "Fall (Northern Hemisphere) / Spring (Southern Hemisphere)" —as Apple advertise it on their own websites depending on region— into the entirely wrong "Q3–Q4", which is a SIX month period of time, and also entirely not 'seasonal based' but 'financial based' so is incorrect.
Yes, pedantic, but these things should at least be correct on there as per Apple's usage, and not the made-up thoughts of some newbie wiki users.
...and I'd say:
Mid-Sep:
- announce OS X Mav release date, then release early Nov.
- announce new Mac's (spec upgrades only this year: haswell/.ac wifi/1TB max SSD in MBP), ship early Nov.
Mid-Oct:
- announce iOS 7 release date, then release two weeks later.
- announce new iDevices (phone/pad ONLY: 16GB touch was only recently updated to 5th gen for same compatibility as bigger models for iOS 7 readiness), with pre-orders the following week, shipping the next week (same day as iOS 7 released).
Similar to last year.
