From the words of KGI Securities analyst Ming-Chi Kuo, Apple will launch a new MacBook Pro later this year powered by Intel’s next-generation Kaby Lake processors and 32GB of desktop-class RAM.
The latest MacBook Pro had came out with Skylake processor and 16GB of RAM.

This new MacBook pro will serve pro users — like video editors — who require more than 16GB and are willing to sacrifice some battery life.

The New intel processor Kaby Lake will target also the 12-inch MacBook. The 13-inch MacBook Pro and the 15-inch models will come out at 16GB of RAM as usual.

Kuo expects the new 12-inch MacBook to enter mass production this spring, while the 13- and 15-inch MacBook Pro with up to 16GB of RAM will follow in the third quarter. The 15-inch MacBook Pro with 32GB of RAM will enter mass production in the fourth quarter, he expects the MacBook with 32GB of RAM to arrive sometime during the second half of 2017 also.
