The current iMacs are 21.5 and 27-inches large, so naturally, speculation has shifted to a 32-inch size iMac, but iMacs with smaller screens will probably emerge, too - and will naturally be more affordable.
The private tweet is translated to say: "The iMac’s screen is really big, bigger than the biggest one."
The new iMacs are sure to also come with Apple's impressive new M1 processor, although whether we'll see a more powerful M1X processor or not is yet to be seen. Another leaker called Jon Prosser has also made the suggestion that the new iMacs will be available in different colours.
Also rumoured to be arriving soon are new 2021 iPad Pro models, complete with 5G, all-new MicroLED display technology, and maybe even the M1 processor.
Whether this means an iPad Pro could run Mac apps is unknown, although given that an M1 MacBook can run iPhone, iPad and Mac apps suggests that an iPad Pro with a truly Pro Mac mode could emerge, and could turn into the ultimate iPad Pro Book, with touch screen, stylus, and with the Magic Keyboard, a trackpad and backlit keyboard, or an external mouse or trackpad.
Perhaps Apple will wait to unveil such a multifunctional device for a future time, or perhaps Apple will never release such a device at all, but it is certainly within the realms of possibility.
Apparently there won't be a full-screen iPad mini as yet, and we are still awaiting the launch of Apple AirTags, which are its competitor to the Tile and other gadgets to find missing tech, along with 3rd-gen AirPods that have been rumoured for some time to look like AirPod Pros but with the same plastic and non-silicon tips as the AirPods 1 and 2, and also without noise-cancelling.
Still, until Apple launches it on stage, it's all just a rumour, with the truth only known to Apple's inner circle and the various parts of its supply chain and manufacturing partners that are sworn to silence - even though leaks do occur.
So, with any luck, a range of new Apple gear is set to launch sometime soon, but whether that happens in April, or not, is anyone's guess.
