BC enchanting questionFollow

Don't know if this has been asked before, but I didn't see it on the main page (though I have been known to miss the obvious before), so here goes. I know D/Eing stuff will know require higher levels of enchanting. Since this means that the required skill is higher, that we can keep getting skillups from D/E-ing stuff longer? I've been really curious, cause I'm not sure if I want to start pumping money into enchanting now, or if it'll be easier (and much cheaper) after the expansion because of longer skillups from D/E.

Sorry if no one here is on the beta and capable of answering the question, but I know I'd just get blasted with spam on the Oboards, so figured I'd try here first....

Honestly, I know the cost isn't that much more than most trade skills when it comes down to it, I just wanted to know if higher tier disenchants gave skill ups now. More a curiosity thing than anything else at this point. In a way, I hope they don't, because if they do there will probably be alot more enchanting competition for those of us who do do enchanting.
