Spoke to a Sony representative yesterday at an film expo, and asked if a future firmware update was coming to fix waveform problem in Cine-EI mode. Unfortunately, he said that that was probably never going to happen. I'm crossing my fingers that he is wrong, but I feel that it would have been announced in the newest firmware coming out this month if it was actually going to happen since so many users demanded it. Anyway, he said a work around was to set a assignable button to the high key/low key feature and expose properly from both, therefore replacing the waveform. I tried this out, but it doesn't seem to work with manual lenses like the Rokinon lenses, therefore making it useless for me. Are there any other workarounds you guys might know of?
