The new footage will be edited INTO the film. A longer version... not a separate feature, like I have seen.
Here is a thread that has a description of the new scenes...

Don't wait, buy them both. There are other features that are included with this one that will not be in the extended, good preview of TTT, other interviews and specials, and some places have it for $15 bucks. I got a card for 10 DVD rentals for free with mine. Cost is not a reason to not get them both! - It's cheap!
You did a lot better than I did...thanks!
The extended version shows up at buy.com for 18.99. Maybe I'll go ahead and pre-order...I'm gonna do it anyhow. Though there's also a sort of super-extended version, no? Tough choices. :-(
