As someone who has them: yes. They were duped a ton during WoD so the argument of them being only obtainable via cards is gone. The market was already artificially inflated with a duping bug. May as well let everyone get it via gold to bnet balance conversion.
I got the normal spectral tiger for 200k and the epic one for 500k in WoD so a lot of people who bought the duped tigers in WoD already got it for less. Cry more.
