It's a gut feeling based on a number of factors, and hints. Two videos, one with a brief mention that Harman can't use the Ilford name on a colour film, the other talking about multi million pounds worth of investment, The Harmanphoto new website, the Harman Phoenix trade name registration, the marketing of the Grey scale Phoenix logo, at the beginning of this thread I said it would burst into colour, and it did yesterday. I'd expect that logo to change into a fuller range of colours.
I suspect that due to the agreements for Harman using the Ilord brand name that includes the IlfordPhoto,website. So it would be problematic listing a Colour film on it, and Ilford Imaging own the Ilfocolor trade name.
Something not mentioned is Ilford/Harman shut-down their coating line for upgrades recently. When I went on an Ilford factory tour in 2007 or 8 their coating line was controlled by an IBM XT running DOS, recent videos show that's no longer the case.
The coating head technology Ilford use was designed and Patented by them, on that factory tour I was in Simon Galley's group, he told us that Kodak and some other companies licensed that technology from them.
So yes the hints are all out there,
