Can the Gen 6 Pokémon games outsell their Gen 3/4/5 counterparts?

There is a good chance of X/Y outselling Black/White. I suppose it will depend of the Pokemon Z announcement. Outselling Ruby/Sapphire is too much, though. ORAS could also outsell HG/SS. Again, Pokemon Z announcement will determinate the remaining Pokemon sales.
