Core format?!

So what cards are in the core format and what cards are not?

Referencing this post from the old forums:

Also here:

Which would make these legal for Core:
# March of the Legion
# Servants of the Betrayer
# Hunt for Illidan
# Drums of War
# Blood of Gladiators
# Fields of Honor
# Scourgewar
# Wrathgate
# Magtheridon's Lair
# The Black Temple
# Naxxramas

Looks like reprints will be legal maybe:
