Corecraft isn't associated with the Nostalrius server, and is still some time away from completion.
Nostalrius does intend to upgrade their servers to TBC, but it is probably years away from happening. When that happens everyone will be given a choice between staying vanilla or doing TBC. At least that is what the team have said so far.
In short: If what you really want is to play TBC, then maybe you'd be better served with playing on a TBC dedicated server.
