I feel like it's going to lean a lot on more current stuff, and a lot of action, which is going to make it a good bit different than the book (they've already stated it's fairly different). What will be missing, and what I think made the book great, was the actual "hunt" for the egg, the mystery and problem solving, and the history behind all the games and movies. It ramped up as the book went on for sure, but it was actually fairly steady. I'm also curious how much time he'll spend outside the oasis. He doesn't really start leaving for extended periods of time until the last half (again). Trailers are only trailers, so I'm hoping they're just showing the "exciting" parts.
