I stand corrected on the storage area, my source that said it would be used for storage has confirmed there will in fact be a year round walk through. The Walking Dead is what they heard as the theme. I can't for the life of me figure out how they plan to house the queue and attraction inside the building. With the new shops and coffee house a large amount of space was consumed. I can't see them using Baker Street for the queue with the amount of people that will have already flooded the park for Potter. Maybe the attraction will be a lot smaller?
