this could have been a play for them to make it more mobile friendly. We tossed out a site that took a designer, copy person, and a developer years to build for a word-press site that took 8 weeks with FAR better results, and it was mobile-aware right from the start.
I can truly imagine the cost of maintaining their proprietary site (cause I been there). Even though it was sharp, it was probably not worth the costs and effort...
