In 2008 there was an epic expansion plan for Valley Fair mall that included 500,000 SQFT of additional retail, including two new anchors: Bloomingdales and Neiman Marcus. Unfortunately, the great recession postponed those plans indefinitely. Now it looks like the Valley Fair expansion is about to restart. Last week when Macy's announced that it was closing its Valco store, it also announced that a 150,000 SQFT Bloomingdales is coming to Valley Fair and would employ 250 people. They even provided an expected opening date of fall 2017.
I can't find the original map that showed where the new stores would be, but can tell you that the original plan called for a third concourse in the highlighted area below. If they go by the previous plan, the expansion will also include 50 new stores, outdoor Santana Row-like dining areas, and 3,000 new parking spaces.
