Found this exert on BANC Group's website. If they are indeed looking to add residential in the near future they'll need a rezoning or development agreement. This could be something to keep an eye on in 2013.
"One of the hottest areas of growth in HRM, Bedford Commons sits on 225 acres of mixed-use land just off the 102 Highway. As a community and retail power centre, Bedford Commons enjoys the presence of many major retailers such as Walmart, Canadian Tire, Winners, Staples, Sport Chek, Future Shop, Dollarama, and many others. Further expansion of the area is imminent, as BANC is pursuing plans for 50 acres of residential development as part of the power centre. Additionally, the park will house the Daniel Nestor Tennis Centre, the largest of its kind in HRM."
