Month old info, but . . .

Cockpit configs purportedly discussed with Boeing included 787-ish (from KC-46), 777, couple variations of production 767. The ISS from our 757 was a non-starter (Boeing does not want to be the OEM of that system).

Inclusion of one of the 767 configs would mean a stop work on the current 757 ISS installs, to coincide around 767 delivery, mod of further 757 to that config, and retrofit of ISS aircraft.

All of this has probably changed as the initial buy from these discussions was 45 aircraft.

Therefore we will probably get a turn-and-slip with a yaw string on the windscreen.
