As for annual passes, keep in mind that Universal's expenses have also gone up with increases in minimum wages paid by all Orlando parks, additional security, etc. Passholders always are demanding, want everything for as little money as possible, and end up really not helping a park since most of them are locals who won't spend any money at the park when they do visit, just ride rides and make lines longer.
I would guess they will cap attendance at VB to a fairly low number each day and keep it a good experience for those who are there. If you suddenly have thousands of passholders showing up each day to just ride the water coaster or their favorite slide over and over it spoils it for the people who are resort guests and spending thousands of dollars (who will always be the priority).
As I've been saying for months, expect high prices for day tickets (close to or even with the other theme park tickets prices), and IF they even offer APs or add-ons to existing APs they will be pricey. They will not want the local riff raff there using the park as a babysitter in the summer. Expect that may change in the off season or after some time when they know the limits of the park. Look at what they did in Hollywood with the opening of HP as a guideline.
