With the Gold Class 710 just coming out, I don't think it will happen any time soon, if it does at all. I have noticed Benchmade generally does not release new or updated Blue or Black class models concurrently with their Gold Class ones (same goes for many others makers).
I wish they would and even more so wish they would make the CPM-M4 models a standard production run given M4's toughness on that sort of a knife is a big plus over most other steel options. The crazy secondary market prices for the M2HS, M390, and M4 models show there is a pretty big user-demand for upgraded steel options on the 710, and I am really impressed how much of a performance gain my 707 in M390 is over my 707 in D2 or 154CM.
