The Imperial Knight leaks have upset someone, and it looks like the rumor lockdown is once again in full effect. This of course makes information much harder to come by, but we have all been through this before.
Please remember that this information is rumored, and was sent in to this site as such. Salt is always required.
I think it was quite obvious that leak was a big one, after all these are new models and a new Imperial Faction. The cat was out of the bag a little early on this one, and I have removed the where or who was mentioned in this email to avoid the drama.

Things are on information lock-down at the moment. Some bigwig at GW is furious about the inside source for the Knight rules leak. It's codex BA all over again. Nobody at GW appreciates or tolerates this.
They worked very hard to keep the Knight out of the spotlight and now everybody already knows about it. These leaks might even affect the release schedule, "soft" releases like the Chaos Chosen might be put forward and "hard" releases like the new IG pushed back. GW knows that they don't have any control over the last 48h, but they are adamant to do whatever it takes to make sure that their announcement will be the first in the future.
