While Apple has not confirmed that they are working on a new Apple Mini-LED iPad model, new rumors and speculations are suggesting that it might actually be arriving next year.
According to 9to5Mac, analyst Ming-Chi Kuo has reported that the new tablet will be arriving in 2020 or 2021 and that Apple will be releasing the Mini iPad as well as a 16inch MacBook Pro.
He also added that the iPad Pro will arrive first in Q3 of 2020 and that it will come running on the updated A14X processor. The MacBook Pro, on the other hand, will only be arriving in Q4. He also thinks that Apple will be releasing more Mini-LED hardware in the next two to three years.
Of course, at this point, all of these are just rumors and speculations so you might want to take it all in with a pinch of salt while we wait for Apple to make an official announcement.
