Everything you need to know about Apple's next launch event on 21st March

Hear that?

It's the growing rumble of Apple rumours frothing like a raging tide ready to break when their next launch event happens on March 21.

Here's a roundup of all the info and tech the foremost gadget gods are expected to shower on their loyal followers.

When's it happening?

The week of 21 March 2016

At least, those are the noises coming from several Apple-friendly sources.

Korean site UnderKG News believes that the event has been delayed by a week, pushed back from 15 March to the week of 21 March - possibly in order to polish off some of the reveals and demonstrations.

Their source has pointed to an event being held on either 21, 22 or 23 March, following an internal memo sent to various Apple staff to leave these dates available in their schedules.

A 4-inch iPhone

No one can agree on the name (it's either the iPhone 6C or the iPhone 5se) but it's looking increasingly likely that Apple is set to scrap production of the iPhone 5s with a new 4-inch model.

Features:

• 4-inch screen
• NFC for Apple Pay functions
• Rounded iPhone 6-esque design
• New camera
• New processor
• No 3D Touch screen

iPad Air 3

While the iPad Pro wasn't the runaway success they might have hoped it would be, Apple is still keen to squeeze more functionality (and money) from a new 'regular' iPad.

Features: 

• A new A9X chip
• Thinner build (yep, thinner than 6.1mm)
• Stronger aluminium case
• Enhanced camera
• 3D Touch screen

A smaller iPad Pro

Was the iPad Pro just a little bit too big for your liking? Then you'll likely be thrilled to hear that Apple is set to shave 2.2 inches off it for a 9.7-inch version - doubling the devices screen sizes in a similar manner to its 13-inch and 15-inch MacBook Pro.

Features

• 9.7-inch screen
• A9X processor
• Smart Connector
• A smaller Smart Keyboard cover

Two new MacBook Air models

Apple's super-sleek MacBook Air has apparently undergone a full redesign in order to squeeze even more tech into even thinner 13-inch and 15-inch models. 

Features:

• Retina displays
• Super-slim design

New Apple Watch models

While Apple won't be releasing the Apple Watch 2.0 in March, shifts in their component supply chain are pointing to a new aesthetic redesigned timepiece. 

Features:

• New colours for the rubber Sport band
• Additional colours for the Hermes partnerhsip
• A black Milanese Loop model
• Potential for a front-facing Face Time camera
