TRAILER: http://www.youtube.com/watch?v=vP0cUBi4hwE

Well! Thoughts:

They may have compressed the First & Second Invasions into one event. That seems fine, for the sake of simplifying. That being said, the Invasion scenes, Jets vs Buggers, look great.

The trailer does a good job of getting the point across, particularly through Ford's narration. No real telling if this will be a decent performance from him though.

Looks like we might see the surface of the Command School Asteroid?

Valentine & Ender on the lake. Excellent.

And finally, the last part of the trailer: WHY WOULD YOU PUT THAT IN THE TRAILER???
