All the stuff in this link is 100% the real deal. ( Ive posted it below)
As far as 6th ed...
I will also add that vehicles use "hull points" in 6th. If a vehicle has 3 hull points it will die after 3 shaken results, but it can still explode after 1 shot as normal.
All cc weapons have AP values in 6th similar to what was in the fake 6th ed rule book leak.
There are going to be no different levels of Eternal Warrior either.
regarding theDark Generals rumors from earlier this morning.
I'm sorry chaps, there are no legion specific rules. TheDarkGeneral is merely guessing and he is wrong. The best you can do is unlock certain elites as troops with specific special characters. Of which, there are no new ones mate. But they are all pretty good. Ahriman is a bloody psyker mastery level 4 now.
-The "flying dragon thingy" is coming. It is a flyer and one of two entirely new units added to the codex.
-The second new unit is said to be a Chaos answer to the Grey Knight Dreadknight.
-The Chaos Dreadnought is indeed still there (take a breath people), but gets a new name, and a rules overhaul.
-Many of the general concepts from magic from Warhammer Fantasy are coming to Warhammer 40,000.
-Psychic powers will be generated randomly by psykers (like fantasy)
-The FOC may be history
