>>120 film is still in production

To be expected. 120 is also known as Medium Format. I learned on a series of 120 cameras (Zeiss then Yashika TLRs). I had a real case of 'gear acquisition syndrome' over the Hasselblad 500EL/M "twenty years in space" edition.

It's been a 'niche' size since 35mm took over, but it seems possible there'll be 120 after 35 is gone.
