The very first trailer shows different footage to what made the final cut.
bits i noticed:
Derplander isn't scooped by a juggernaut because the dragon turns around and finishes it off.
The juggernauts are shooting non-stop at dragons in the air.
Derplander approaches Silver Tear Lake along with the Elezen chick and the Roegadyn with a Greatsword equipped.
There's a bit more of the aether beam that shot up to the sky and apparently it was going to explode in a big ball of light.
And ofcourse the verse that's shown through the trailer:

"On a Forgotten page of eternity
there lies a land embraced by Mighty gods
Her name....Eorzea
as fates cross, swords will clash
under the eldritch veil of a crimson shadow
Heroes of the realm, take up your blades
to answer the call of Destiny
you must join hands...once again"

red for the bits that caught my attention:
1) Is it talking about Allagan wisdom?
2)It talks about the very first Astral Era like that's the current situation you gonna face but that's not the case as we know.
3)Already mentioning a possible war?
4) A shadow that can only be cast by Dalamud...but this early?
5) Destiny is used instead of the Crystal and what destiny was there for us in the original plan?
6) I understand this is a reference to FFXI but it could mean something else too, we don't know how old our characters are and we could have participated in another big battle before.

Thoughts?
