As we have learned from sources close to the company, Tim Cook at the event will not present a (too) long-awaited Apple smart watch, or by some bracelet, iWatch. Furthermore, as things stand, there will not be any new plans disclosed for expansion of the Apple TV service. What can we expect from the only developer conference concerning the company from Cupertino? According to earlier announcements, at the beginning of June we should see the first official version of iOS 8, as well as the OS X version 10.10.
And since Samsung a week before WWDC announced its conference on products and services related to health, it could easily happen that Apple will devote more time to the new application Healthbook.
