The quality is rather bad.
There is a fan-made trailer though; it's really good and combines new material from different sources, nearly all probably from the EE

I've found a fan-made trailer. It has a glimpse of a lot of new/altered scenes. It is almost 6 minutes and you have to save it to your computer but it’s worth it! The website is: http://www.rotk-see.de.vu
The EE version will be 258 minutes long, that is (deducting the time the fanclub-credits take) around 50 minutes longer than the normal edition.

Though a short new scene can be found in a video of the mattepainter Dylan Cole - Frodo and Sam in their orc clothes:
