New Skylake MacBook Pros coming October 27.
iPhone Media Event All But Confirmed for September 10
AllThingsD has an excellent track record with such reports, suggesting that the event will indeed take place on that date, but in case there was any doubt, The Loop's Jim Dalrymple is now confirming the report with a simple "Yep" post.
Dalrymple is well connected at Apple and has on many occasions either confirmed or refuted other reports and rumors in simple one-word posts with 100% accuracy. Such reports are generally taken as coming directly from Apple but delivered through an unofficial channel.
Official media invitations for the introduction should appear roughly a week before the event.
