So are you FINALLY going to support 64 bit WoW once you see the vast majority of people are on 64 bit systems? 1995 called and they want their 32bit shit back....
Forget it. The "Bossland chaps" decided that it's not worth the effort to have another HB to maintain. And since more and more players are on 64 bit systems, the choice of a 64-bit WoW is obvious, isn't it. And since less and less players are on 32 bit systems, the choice of a 32-bit WoW makes botters stick out like a sore thumb, doesn't it. And since ... ah what the heck .. useless .. stubborn devs.
It's not as simple as just making it 64bit and calling it a day. If it was a matter of simplicity it would be 64bit already.
