LOL.
FWIW, the Canon USA eStore lists the 1D IV, but not the 1DsIII - but that's not new, the 1DsIII has not been available there for a long, long time.
The Canon CA eStore doesn't list any supertele primes, nor even 'consumer' telephotos like the 300/4 IS and 400/5.6. I don't think that means they're all about to be replaced (especially since some already were, and are due out later this year).
