Well, I ordered end of January 2022 and I've been told January 2023 - in fact the car has just been built so that date is fairly firm now I believe. That's 12 months, yours would be 14 months, so not out of the ballpark - especially if it's true that Takumis are taking longer because of the extra bells and whistles.
I ordered through a lease company who told me that they would no longer give estimated delivery dates until a build date was confirmed because the dates changed so much without a confirmed build date. Whilst waiting, I have had estimated dates of August '22, September '22, January '23, April '23, October '23 (!), February '23 and now a seemingly firm January '23, so take any dates with a pinch of salt!
