Here's my insight regarding this issue..
To start, because Deathwing and Ragnaros are currently running the (OLD) WotLK core, players on these two realms have inadvertently drawn the short end of the stick; the QA/Development team doesn't dabble in the old core anymore and although that Bug report states that
http://wotlk.openwow.com/item=37012 doesn't drop, that's not to say that it won't. The truth is, that report was made post-Moltdown and thereby
after Hallow's End took place. Put simply, there's no way to know for certain that the report is accurate with consideration that from Moltdown to Lordaeron's release, the old core has most likely changed.
Actually, I recall even last year some staff members defended the claim that it did indeed drop despite the overwhelming player consensus that it didn't (it was later made available for purchase in the Marketplace).
Don't mistake this for wishful thinking.
Secondly, Lordaeron itself will be seeing some controversy regarding this. Because of the lack of RDF,
http://cata.openwow.com/item=54516 will be unobtainable. This, and the fact that the
http://wotlk.openwow.com/npc=23682 is a level 81 elite, does not bode well for the current level cap of 60, soon to be 70 players.
It will be interesting to see how Warmane responds to these queries as there's no doubt in my mind, Hallow's End is the most beloved world event among players.
