Good question raised but unfortunately without answer. Nevertheless, a part of the studies were done before the project was frozen in 2007. Anyway, today the freighter market is quite bad, China Southern sent his brand new B777F in the desert for long duration storage, Singapore Cargo and Cathay Pacific Cargo, like many other Freight Airlines did the same with their 747-400F. So time is not the best to launch such a product after cancellation of all its orders 2 years ago.
Just wait and see is the word now.
