Gold halving and transfer to Icecrown from Frost

A few weeks ago the information was that the gold will be halved when we move from frost to Icecrown.

I moved all my characters yesterday and the gold is still the same, I asked and every person I asked had the same experience.
I want to ask, will it be halved after the 30th or? I had some BoE drops and I didn't sell them on Frost because there was nobody to buy it, now I'm not sure if I should sell on Icecrown because I fear that the gold I get might get halved in a few days so maybe I should save them?

Is there some verified info about the gold situation, will it stay as it is or is a halving incoming?
