There are 2 reasons I've long thought that the patch *could* be released prior to the AH shutdown:Quote from Narmoniarkh
- New Sets/Legs can't be sold on the AH because of BOA.
- ROS is incoming, so the 2.0 blues/yellows that are found will be easily replaced with level 70 items for those who upgrade.
*Edited to add*
Another thing that slipped my mind earlier is that it's also possible to deny items that drop post patch from being placed on the AH at all. They'd show up much like the BOA crafts do now in the AH window. This way, legacy gear is still tradable, but new gear remains constrained by the trade mechanics of the future.
