I just find funny that Blizzard claimed that PvE to PvP transfers would never happen, listing valid reasons such as "Earn your right to gank by exposing yourself to the same risk" and ""it's unfair to those who level on PvP realms".. whatever happened to that?

I don't think it really about money though, they already make tons of it (sure more is nice, but still), they are trying to kick Warhammer in the shin.

They can't make patch 3.0 go live in time for Warhammer's launch, so they're resorting to these measures.
