Unfortunately, it looks like the new MacBook Pro will not adopt the latest hardware. The device will get a slimmer design, TouchID support and a built-in OLED touch panel, but the first model will likely feature Intel Skylake processors because the device's launch is before the availability of suitable Kaby Lake CPUs:
Intel often launches low-power 4.5W Y-series chips and 15W U-series chips first, neither of which are suitable for use in the machine that people are most curious about, the MacBook Pro. According to an old Intel roadmap, Kaby Lake chips appropriate for use in the MacBook Pro, the iMac, and the Mac mini won't launch until the very end of 2016 or the beginning of 2017, meaning any Apple machines released in the fall of 2016 may be limited to Skylake chips.Source: MacRumors
