Apple may release the second-generation Magic Keyboard in March 2021 with compatibility for the fourth-generation iPad Air
The fourth-generation iPad Pros are somewhat iterative updates over their predecessors. Still, the Magic Keyboard marked the first time that Apple had brought official trackpad support to its premium tablets. The Magic Keyboard has its drawbacks though, namely its price and the heft that it adds to the overall carry weight of the iPad Pro 11 and 12.9-inch models.
Apple is apparently not hanging around with delivering a new edition of the Magic Keyboard, though. According to @komiya_kj, the next Magic Keyboard will be released in March 2021, which will be a year after the release of the current model. @komiya_kj adds that next year's Magic Keyboard will be not only compatible with the iPad Pro range, but also the next iPad Air. The latter is rumoured to feature a refreshed design and one that is closer to the iPad Pro than the current iPad Air.
@komiya_kj has not offered any details about the changes that Apple will make to the next Magic Keyboard, nor whether it will release a dedicated version for the iPad Air. However, the fourth-generation model is thought to have an 11-inch display, which should make it compatible with the Magic Keyboard for the iPad Pro 11. A larger trackpad would seem like a reasonable change for the next Magic Keyboard, as would a reduction in its weight compared to the current model.
