I don't expect anything from this announcement to "forever change how photographers create their images". That's pure hyperbole.
HSS 645 LS lenses would be ground breaking for Pentax in that they'd complete a missing part of the MF equation. It's sort of the reverse of how we've had FF glass but no FF DSLR; we've had a MF DSLR but no high speed capable MF leaf shutter lenses from Pentax.
I have no reason to suspect that leaf shutter lenses are going to be any part of this announcement but I have a hard time not dismissing any argument that says it wouldn't be a big deal in the medium format world for Pentax to release new LS lenses.
