it sounds like the diesel Tundra/Sequoia will be very, very expensive... more than the usual difference overseas.

I can understand why they're not willing to combine diesel and hybrid in a pickup truck.
But for a diesel pickup they probably still don't have the engine ready. The 4.5 V8 diesel in the current landcruiser is two car engines (see toyota avensis diesel) moulded together. They'll need something more abuse resistant to go head to head with cummins and co.
