Apple Confirms March 21 Event and Offers a Clue About What's in Store

"Let us loop you in," the invitation reads.

Invitations were sent out today for an event to be held at Apple's campus in Cupertino, California, on March 21 at 10 a.m. PT.

Apple was characteristically coy about what to expect but offered one clue, teasing: "Let us loop you in."

Over the past year, Apple has introduced super-sized iPhones, but the company's next release could be getting smaller.

The rumored new device would be about the same size as an iPhone 5s but would come with some of the newer design and software updates found in Apple's past two releases, the iPhone 6 and iPhone 6s, including a faster processor, photo and video upgrades and Apple Pay capability, according to reports.

It's also expected Apple will introduce a new iPad and possibly new Apple Watch band options (perhaps that's the loop-in clue?) and a number of hardware and software updates.

Let the countdown begin.
