It's not like that at all. With BC you got access to be's and goats which you needed to have to be a shaman/pally. Since they are changing the class availability to different races that you have access to without cataclysm, there's no reason to believe you need it to pick a specific class. Taurens will be able to be paladins so you should be able to be a tauren pally without any xpac.

I bet you will be able to create the new combinations soon as patch 4.0 comes out which should be a few weeks before the cataclysm release. You won't be able to make any goblins or worgens until you buy it.
