Look's like they're shooting for a 2010 release. The "test" trailer they made for COMICON (movie wasn't confirmed at that point... was just some 3D stuff to show off) was so well recieved it was greenlighted immediately and they started work.
All the early stuff I've seen sounds good.
There's a bunch of stuff out there about it on Comingsoon.net and Aintitcoolnews.com ... and if you do some searching you can find bootleg versions of the Comicon trailer (it was never released).
Can't wait to see things as they officially start promoting it... but TR2N is confirmed.
**Edit: Here's the test/teaser they showed at COmicon but it's a filmed version... as of right now there's no original copy version since this was something they threw together for Comicon before it was 100% confirmed. http://teaser-trailer.com/2008/07/tr...r-version.html
