This seems highly likely. OS X used to come out in July & August, and only recently has it slipped to September and October. What if they get it back to July & August this year? Then they can announce the new MacBooks but not ship until July or August, and give developers a chance to integrate the TouchBar into their apps, or shortly thereafter, without giving the competition much lead time to rush something to market.
This would make sense to introduce the new 2016 models or at least announce next week to balance out the year's releases.
Developers will have time to develop for the 'back to school' purchases and Holiday seasons. Also Gives time for people to desire to buy in the fall and anticipate for the holidays. This type of strategy is a Mac centered focus, but apple instead is focusing on iPhones (profit generating) and watches.
Of course profits are great, but come on..how much is "enough".
It's time to 'wow' the consumer with something great to buy in the mac product lines!
