It seems previous threads about the new Portra 400 got somewhat derailed.
I have recently shot my first 120 roll of it, and my first impression is that I am absolutely amazed at the tonal range it captures. I shot a very, very high contrast scene in which I would have expected either washed-out highlights or a total lack of detail in shadows, yet there was plenty of detail in both.
I haven't printed optically from these neg yet (I'm only just getting set up to my first ever RA4 printing this week) but I can't wait to try.
I'm really looking forward to seeing what else I can do with it, but so far the new emulsion has certainly exceeded my expectations.
I look forward to hearing others' experiences of the actual use of this film (rather, really than the politics around it. I have plenty of opinions there but those are perhaps for another discussion), as well as of the new 160, which I have yet to get my hands on.
