According to asus they will. Until the P5 changes socket at least.

That's right, but the Prescott will rapidly morph to the new chip and
socket that uses tiny "spheres" instead of pins, so the upgrade path
with the P4C800 will be relatively short. The one upgrade you get may
be pretty significant since even the early Socket -478 Prescott will
come with a 1-MB L2 cache.
