The NUMMI plant in CA makes the Pontiac Vibe and Toyota Matrix. The Vibe is 99% a Toyota Matrix with some minor differences in styling and trim. So this is, very definitely, rebranding.
Most, if not all, of Bergger's products were just re-badged Forte products as can be confirmed by reviewing a Forte product catalog from the mid-90s or earlier. A very small minority of those products were probably designed by Filmotec. Similarly, I expect the new Bergger products will simply be Ilford wares in drag - at Bergger's traditional markup.
I really do hope I am proven wrong in this, but I suspect that I will not be.
Only time will tell.
