There remains a short wait using the Express Pass line at some attractions, but the longest I ever encountered was a little under 10 minutes at Revenge of the Mummy, when the "regular" line was running close to an hour.
The biggies missing from the list are Rip Ride Rockit at Studios, the Enchanted Unicorn/Hippogriff youth coaster at IOA (currently being rethemed), and the upcoming Harry Potter & The Forbidden Journey attraction at IOA. Dueling Dragons is still included, but I do not know if it will stay on the list when it reopens as Dragon's Challenge later this year.
My guess is that RRR will make it on the list once it is operating at the original planned capacity (hopefully soon), and the three Harry Potter attractions will make it sometime in 2011 (Hippogriff and Challenge probably a lot sooner than Forbidden Journey).
-Hotel Accomodations On-Site
-CityWalk Party Pass
-Universal Express Pass
-WWOHP Grand Opening Commemorative Ticket
-Breakfast at the Three Broomsticks
-Early Entrance into Islands of Adventure (attractions listed open during 1 hour period include The Cat In The HAt, Flight of the Hippogriff, Dragon Challenge, and HArry Potter and the Forbidden Journey)
I think I have found my "express" pass into WWOHP!
