A poster in the general forums today outlined his, and many others, money making strategy they'll do when patch 3.0.8 goes live:
- Save up bank-tabs-full of Relics of Ulduar
- Sell Relics of Ulduar when they are no longer soulbound in patch 3.0.8
However a response by Bornakk, a Blizzard Community Manager, reads "Is there a problem? Yes sir, the data on the relics is inaccurate. While things can still change, they may remain souldbound."
So in the typical Blizzard fashion of not confirming anything outright, they have more or less strongly hinted that relics will remain soulbound in 3.0.8. So much for the money making scheme.
