Still roaming the wastes of Azeroth, checking under every rock in the way, looking into every possible wormhole I can find but no sign of ya, https://classic.wowhead.com/npc=16030/maggot !!

I would be shocked if our characters would not move onto TBC. It's against everything that Blizzard does with how they work expansions. The question more in my mind is, will there be a classic vanilla server that remains for those that want to do vanilla but also TBC. We'll see how it all pans out.
