I've read comments that say they do not expect this technology to help DSLRs much. The reason they're useful in compacts is due to the very small pixel pitch of compact sensors. The circuitry that goes before the light sensitive layer really affects the efficiency of light transmission. With DSLRs on the other hand, the pixel pitch is a lot larger. Thus the circuitry that goes before the light sensitive layer doesn't obscure as much light.
All this is just speculation and hearsay for now. I guess we'll only know for certain what kind of noise performance we get from the new sensors. To be perfectly honest, even if they make no difference to DSLRs it could open up a new generation of good low light performing compacts and I could always use one of those
