Wear & Tear vs Replacement relief after April 2013 - change?

It's been the case that landlords letting furnished property could claim either the 10% wear and tear allowance, or the replacement relief, which I know is a concession by HMRC. I'm also aware that:

"Whatever basis is chosen must be followed consistently. It isn’t possible to chop and change between the wear and tear allowance and the renewals allowance from year to year."

Fine. Always stuck to that, however Nichola Ross Martin recently wrote an article saying that HMRC are withdrawing the replacement relief from April 2013. That being the case, a taxpayer previously using this method MUST now "chop and change".

That being the case, can we do it now in 2012 if we know the other method is effectively defunct?

Any idea?
