You can take a look at the buyer's guide for a broad overview of mean times between refresh as it relates to other Apple notebooks. Take a look at the availability of cpus and Apple's implementation of them, and you'll see that it varies considerably. Sometimes official launch dates differ by several months. I'm not sure exactly when the Skylake m types ship.
Thanks for the link
It seems that they update every 200-300 days if i read the page correctly.
But this time, the release of skylake will be very close tothe previous release - broadwell - because Intel could not release broadwell on time.
Therefore, it seems that the ordinary schedule - update cycle, will not be the same this time around, thats why am asking this question here.
If they do not update it until September i will have to 'settle' with the macbook pro 13inch , which seems outdated if we take into consideration the new design of RMB.
Tough choices to be taken
