Yes. Taking a 10-15 year timeframe from Boeing publicly signalling intention in 2011 that would mean the new aircraft would have gone to market in early to mid 2020s. Perhaps no one in sufficient interests in Boeing read Irrational Exuberance [1] which covered in a decent amount of detail about downturns +/- 2 years of every decade, always the same root cause if different symptoms.
