Probable delay for Anna and Elsa from Frozen in Epcot's Norway Pavilion

I've been informed by a trusted source that it's likely that Anna and Elsa may not make the Disney originally posted date of November 1st.  Disney is trying to work through some details and the meet and greet may be delayed to an unspecified opening.  Disney is trying hard to get the experience ready for guests, but don't book your days in the parks around this new meet and greet until further notice.  Disney is even taking the step to reprint the Times Guides to remove the previously published Friday opening.
