Canon to use Sony sensors on their future DSLR cameras?

Canonwatch reports:

“I hear that Canon is considering to sell off its sensor fab and acquire from other manufacturers the sensors of its future cameras. Furthermore, I learn that an EOS camera currently in testing is being tested with two different sensors, one made by Canon and the other one made by another sensor manufacturer.”

It’s quite obvious that if the rumor is true that this means Canon is testing Sony sensors. But I don’t think it would make sense for Canon to switch to Sony sensors. They would always get the best sensors a long time after Sony’s own camera implementations.
