The second trailer is awesome, especially the showing off of the new techs. It's also deceptively sweet that people will think Frog is in the game for now.
The only part I'd keep out and replace with something else is the snippet for Project Anabasis. Belthasar's lie depends on the party and player believing that the Frozen Flame wasn't used in the reactor. While viewers of this might think while playing that perhaps this scene took place in the future, it's still betraying a little too much since King Zeal's already the villain during the game's events, and the scene itself is colored yellow (the "flashback" color in anime).
The third trailer, hah...we'll have to preview Chrono'99's Neo-Epoch. People will go nuts.
