Well-known Apple analyst Ming-Chi Kuo expects the upcoming MacBook Pro and MacBook Air line to be fitted with scissor switch keyboards owing to the good feedback received from users of the 16-inch MacBook Pro. Kuo also predicts that Apple will start using its own custom SoCs in MacBooks to be released in late 2020 or early 2021 along with a complete redesign of the MacBook lineup in late 2021.
