In body IS
Canon are looking at in-body IS for the entry level range DSLRs.
They have worked out how to integrate it with the lens IS so that the in-body IS turns off if a lens with IS is attached and the lens IS is active.
There is no definite decision about its appearance - however it could be added to the 2nd generation 400D replacement (the 450D is already pencilled in for Jan. 2008)
Technologically, this could also be added to any other DSLR. However at the moment, Canon's engineers are opposed, believing that all those moving parts around the sensor is not good on a high end camera.
