Question About Halo 4

Are they ever going to add the Acrophobia Skull and Bandana Skull to Halo 4

In the “Halo 4 Tenth Anniversary” blog post (early November) they said:

“We’ll also be implementing new skulls to the game, namely Acrophobia and Bandana, along with golden moa collectibles in the campaign and some legacy multiplayer perks that haven’t yet come to MCC.”
