Board Thread:Speculation House/@comment-82.12.156.248-20140310081810

So, because I got talking about Blake's motivation to stay with/leave the new White Fang I decided to see if I could find any actual evidence to timestamp when she left the organisation. Logically this place itself seemed like a pretty good place to go since the mods seem very particular about what they post as true/canonised on the wikia and have no qualms with actively labelling speculation as exactly that until we get official word. However I noticed one thing:

http://rwby.wikia.com/wiki/Timeline_of_Events#Events_Before_Current_Timeline

Is there any citation that proves that the events of the Black trailer took place one year before the events of RWBY? And if not can someone go back and either label that as speculation or timestamp it as "Unknown time before the events of RWBY"?
