According to Emmerich:
"We're trying to do it as a big mini-series, but even there you would have to change the story itself and set it in a time when the galaxy has fallen apart - and then you're pretty much making a TV show with all these characters and playing all the scenes out. You can [do that] and we'll see what happens. We tried so hard [to make it into a movie], honestly, because it's one of my most favourite books. I just love it."
Here's a thought. If you love the book so much, why not just do an adaptation rather than arse around with it? If anything, the episodic structure of the books (the first three 'novels' in the series are actually linked collections of short stories and novellas) would map onto a TV series very well.
This is still early in development, with no writer or studio yet attached.
