At least the RH is available in the US, several new owners have posted here. I haven’t found a LH fitting head, yet to try.

They should still be available. I got mine last fall when the new models were released. Not sure if you are trying to order directly on the website or through an authorized dealer? Hope you get it figured out. I also made sure and did a fitting at TPI where my set was 1/4 inch longer and 1 degree stronger than standard. Fitting is really important, especially in these weaker lofted irons.

Are you in the USA? RH is definitely available. None of my local fitters has the LH fitting head but that doesn’t mean they aren’t available.
