Hi Mark Anthony.
As Fuji has pulled its 800 film, I'm hoping Kodak will be able to maintain the 800 Portra as it will be about the only quality print film at that ISO point as far as I'm aware. I've been using it recently (as I couldn't get any of the Fuji variety) and it's a lot better than I imagined it might be.
The point you make about scanning and (I'll add) post-processing via the likes of Lightroom will allow us to be as true to (or creative with) the colours, saturation and tonality as we feel appropriate.
I know it's not the heralding of a new age of film but, to me, it's positive news and a commitment to keep at least one top quality 400 ISO film available.
