Sources say that this event will likely focus solely around the new iPhone, iPad, and Apple Watch announcements. However, both new 12-inch MacBooks and upgraded MacBook Pros are in the pipeline for this year. Faster MacBooks are in store for debut by WWDC, potentially in April or May, and new MacBook Pros coming by the second half of the year. Sources say that Apple has considered announcing new 12-inch MacBooks at this event, but the imminent release currently seems unlikely.
As always we will have live coverage of the keynote and will keep reporting the news as we get it ahead of March 21st.
