Also the P-Town center has much shorter buildings. It is really meant for retail in an urban form. Comparing the retail side is not really viable as much of the anchors are left over from the old mall. Compare the apartment/condos as well as office space and schools in terms of square feet as well as numbers of corporations. The Peninsula town center is more of an urban mall for suburbanites but also containing a bit of housing/office.
Its like comparing an apple pie and a birthday cake, the former has more apples but the latter is what you really want overall.
Also, the Peninsula Town center form is what we will probably get for the Pembroke midtown area, right now we are building up the CDB, which is a much greater anchor for a downtown.
