Bad Career Move for Bale?

It has been officially confirmed that Christian Bale will be playing John Connor in the new Terminator movie entitled "Terminator Salvation: The Future Begins." This is supposed to be part 1 of a brand-new trilogy envisioned by producers Derek Anderson, Victor Kubicek, and Moritz Borman. http://www.ew.com/ew/article/0,,20164286,00.html

Why did Christian Bale agree to appear in three big budget action movies directed by McG (of "Charlie's Angels" fame aka he is not particularly well-respected)? Bale is a great actor and can convincingly portray any character he wants. He already has a big budget iconic character in the bag with Batman. I would think that role would take care of any action, monetary, etc type of desires he may have, leaving room for Bale to also act in smaller, edgier films. But now that he's committed to the Terminator movies and the Batman movies, how is going to have time to do anything else? He's so method too that I fear he will start believing we are living in a post-apocalyptic world and start making tourniquets out of shirt sleeves and screaming "Come with me if you want to live!!!" in his everyday life.
