I highly doubt that. Kaby Lake in the version Apple wants won't very likely come before next year. When has Apple let one of its main product lines, MBPs, left un-updated for close to two years? As much as I can remember, never. My guess is that if you had asked Apple a year ago when they planned to release new MBPs (and they had answered that question), they would have said June-ish. Some component, note that this a new hardware design, must have slipped which delays things by a few months. I don't really buy the Sierra argument (ie, that new MBPs are delayed because they need software features that only exist in Sierra). Apple knew already a year ago that Sierra would come out in the fall (pre-viewed at WWDC with beta releases following shortly after that).
