they announced these would be era TBC servers

The announcement thread stated:

@Kaivax

We’re particularly excited to reveal that Normal (PvE) and PvP fresh Anniversary realms will progress to Burning Crusade Classic, after we progress through the Classic Era content phases.

But doesn’t make mention that Burning Crusade Classic servers would become Era servers.
