Watch and discuss the first Ender’s Game trailer

The first trailer for the Ender's Game film is here, and I don't have much to say. Harrison Ford never seems like a character any more, he just kind of seems like an old Harrison Ford. The ages of the children also seem to be advanced a bit, but that's not surprising. Also, are we seeing what I think we're seeing in that last scene?

There is much about Ender's Game that seems unfilmable, such as the games he plays on his computer, the relationship between his brother and sister... I'm trying to be vague, but let's go ahead and make the comments a full-spoiler area for the book, since I'm curious about your thoughts.
