I'm sure this was square's intention, but I wholeheartedly feel that had this been the original Dawn trailer, there would not have been half as much uproar and such.
The original trailer was quite lackluster, and didn't set the tone for much of anything, where as this trailer definitely captures more of the emotion of both Noctis and Luna, and even more so of Regis.
It was admittedly short, and only SE would ever release a 2.0 of a trailer, but I think it was the right thing to do. It set the record straight, and helps to get their marketing push going in the right direction. It may have been too little too late for some people, but I also suspect that those people may be the type to just go on media blackout from here on out. If you think the trickle of info is not for you, I completely understand. The original "Dawn" killed a lot of the hype for me, but I feel like the fact that they were able to get back on message helps things, and hopefully is a sign of good things to come.
