It's sad this has to be a rule but I'm glad it is. The Bills threads agravate me to no end and I could not agree more with the points raised in the OP. As for the early release point, not much has been released about the extent of Bills' abilities so I'd much rather wait until the film officially comes out before seeing what Bills can do. Of course this will result in inevitably more arguments but at least there'll be something to base it on. Even then, we'll only have translated speech and a few leaked clips to work with since an English release hasn't even been confirmed yet. And are there any Japanese users on CV?
The thing that'll really give us a lot more information will be the Japanese DVD release. And god knows how long that will take. The nation wide release on the 30th probably won't make the information any more readily available than it is right now.
