No news on updates to the Surface 2-in-1 models, despite their latest earnings showing a 26% revenue decline from their Surface line.
They claim the decline is due to more competition, but I'd say it's mostly because the Surface Pro 4 is from Q4 2015 so it's 1.5 years old which too much for a supposedly state-of-the-art line of devices.
I'm hopeful that a Q4 release for Surface Pro 5 will mean Raven Ridge APUs in there (it'd fit the roadmaps), though I don't really think Microsoft would be open to risking the media/public backlash from downgrading single-threaded CPU performance between SP4 and SP5, even if it meant 4-5x better GPU performance.
