The mods are locking all threads that even allude to it, but that's it as far as 'official' responses go.
We'll lock threads about the leak, but at this point mentioning it isn't sufficient. So if someone wants to discuss character animations, and people mention what they saw in the leaked video, we won't lock the thread down for that. Now if the discuss turns towards discussing the leak itself, rather than animations, it will get locked - and often a mere mention is enough to get a discussion off track.
