Apple is expected to unveil two new iPads at a press event on Tuesday, revealing the fifth version of its iPad tablet as well as the second iPad mini.
A new Mac Pro desktop computer is also due, as well as a release date for OS X Mavericks, Apple's latest Mac operating system.
Invites for the California event, which will be simulcast in Japan and London, did not give details, teasing with the line "we still have a lot to cover".
The new iPad is likely to follow the lead of the iPhone 5S, unveiled in September, which features a faster A7 processor – the processor for the iPad 5 would be the quad-core A7X, speeding up graphically intensive games and high-resolution video playback.
The iPad, which already includes a high-quality 'retina' screen, is thought to be much thinner and with a slimmer 'bezel', or frame more like the latest iPad mini.
The new iPad mini is expected to feature a retina screen upgrade, while rumours of a gold back – like the iPhone 5S – have largely been dismissed.
Touch ID, Apple's fingerprint-reading access feature, is expected to be added only to the iPad 5.
Apple is also due to announce release dates for OS X Mavericks, its new software for its desktop computers and laptops, and the Mac Pro, its remodelled, high-end computer which will sell as part of a basic system for around £2,000.
Less reliable predictions from analysts and the supply chain have claimed a cover with built in-keyboard is in the works – hence the invite line about 'we've got it covered' – along with a new Thunderbolt external screen. Apple has not introduced a new display since 2011.
