Codex Leak Conjecture

Based on the leaks we've seen today from the codex and the associated data sheets, are we of the opinion that the codex was written pre-field manual/FAQ?

Things like Lord Solar written as being able to order ASTRA MILITARUM units, not Squadron and Regiment etc.

Edit: I'm huffing the copium that my scions (Of which I just got 60 of) haven't actually lost deep strike, but that the lack of deep strike ability is a TYPO.

It also appears that there's a lot of typos as far as keywords, rules, abilities and stat lines goes (DKOK watch master using a bolt pistol or boltgun, data sheet says both and contradicts its self).
