The hardest, and probably nearly impossible, guess is when Universal will make announcements. They're all over the place on those. Absolutely no guess on that from me.
...Good to hear you read the Jay Bangs book. You now probably have a better understanding how Universal thinks & operates than the vast majority of theme park followers. Genneway's Universal book that preceeded the Jay Stein book, is also a great source of information & understanding. Additionally, if you study Comcast's corporate history (I've followed them since they were just a small regional cable operator), you will understand how opposite their corporate philosophy is from Disney's. They only know one speed, "full steam ahead", which really is a nice fit with the MCA/Universal philosophy of the Lew Wasserman era.
