No Peaking Level on verion 1.00 firmware on NEX-7, why?

Just received t he NEX-7 yesterday in Hong Kong, when going thru the set-up, found that " Peaking Level" is there, but cannot be enabled. The camera is with firmware 1.00, will Sony provide a firmware up-grade soon to provide the "Peaking Level" feature like the NEX-5?

This is an important feature for MF, and NEX-7 is a good camera for using adaptors to make all old MF lenses alive, so "Peaking Level" is required!
