Additional evidence has been found pointing to the possibility of a 16-inch MacBook Pro notebook in the works.
French website MacGeneration has located references to the rumored 16-inch MacBook Pro. Looking similar to the current 15-inch MacBook Pro, the notebook appears to feature a thinner bezel.
Per the article:
macOS 10.15.1 contains references to a MacBook Pro 16″, which accredit the many rumors about this new model. In the code of the first two beta of this version of Catalina, we found with the help of a reader, Maxime, the mention “MacBookPro16,1” which designates a new laptop of 16 “. Better than that, there are even the icons of the machine!
Stay tuned for additional details as they become available.
