I don't see why it makes no sense. The 2018 / 2019 model has more features and capabilities to sell than the previous one due to more suare mileage and the SRK road test report.
Maybe JB just isn't as desperate as many of the long-suffering shareholders. Truth be told, he knows a LOT more about what he is offering than we do.
I'll trust his judgement. If I can't, I should sell / should have sold.
