I will probably pass on MFL only because I am satisfied between the current release and the laserdisc box set. I am all over the other announced titles, though. Thanks, WB!
Whether a transfer of a large format film is from a reduction or not is academic to me. There are more than one ways to skin a cat in making a superior low-rez video presentation, and there are a lot more noticeable things that can be wrong with a transfer than any artifact of a single generation downconversion to 35mm.
I believe Vertigo is probably the only Vistavision film that has ever been transferred from a large format source for a home video master (a windowboxed element created from the Vista to 65mm restoration), but I don't plan on boycotting other titles because they did not make a 65mm element from the VV negative for transfer. Let them make the video master however they like and I will judge it based on the results, not the method.
