This is in his latest Power On newsletter where he claims that September to November is a possible launch window for the laptop, although if we had to posit a guess, it might be late October or early November. This is because September is when the iPhone 13 will launch and we doubt that Apple will combine both the iPhone and MacBook Pro announcement together.
This leaves late October and early November which is not only when Apple launched the M1 Macs last year, but it is also when the company hosts an event in the year for refreshed iPads and/or Mac computers.
That being said, according to the latest rumors, the redesigned MacBook Pro will come in a new 14-inch form factor (along with 16-inches), support up to 32GB of RAM, support for a UHS-II card slot, and it will also come with upgraded 1080p webcams.
