personally I've only invested any amount of time into my classic hunter strictly because of the potential of transferring it to tbc. Am I super rich? no, but I have a decent character ready to go in case we go that route.
Alternatively, if they take the fresh start or instant-58 route, I'd be fine with that too. Vanilla doesn't interest me much, my love for wow truly started when TBC launched, before then I really didn't care much for wow, it was something to do with friends.
