Apple occasionally has events in March or April to announce something new. Sometimes, Apple introduces new products. For example, on April 20, 2021, it was a “Spring Loaded” event to announce the 2021 version of the iPad Pro, the AirTag, and updates to the iMac and Apple TV. Sometimes, Apple introduces new services. For example, on March 25, 2019, the tagline was “It’s show time,” and Apple announced Apple TV+, Apple News+, Apple Arcade and the Apple Card. Yesterday, Apple revealed that it would hold its next event on March 8, 2022, at 10 Pacific / 1 Eastern. This will be yet another online-only event, which means that Apple has been putting together a series of video introductions, and the recordings will be streamed on Tuesday. The tagline for this event is “Peek Performance”:

What will Apple announce? Only Apple knows for sure, but I have some guesses. We know that Apple will introduce additional Macs at some point in 2022 that take advantage of Apple’s powerful M1 chip, and perhaps an M2 successor, and the reference to “performance” makes me think that new, more powerful Macs, could be announced. The word “peek” suggests that maybe we are just seeing a preview of something that is coming later.
There are also rumors that Apple is ready to announce a third-generation iPhone SE. (The second-generation model was introduced in 2020.) There are also rumors of a fifth-generation iPad Air. (The fourth-generation iPad Air was introduced in 2020.)
Perhaps Apple will also devote some time to iOS 15.4, which will add lots of new features.
And just maybe, Apple has something new up its sleeve that nobody has predicted yet. We’ll see.
