If I was Leica, the last thing I'd want would be to have several thousand M8s arriving on my door-step for re-work, even if on a scheduled basis in the run up to Photokina. The opportunity for bad publicity is huge if things don't go right.

Seems likely the upgrade program was conceived by Steven K Lee who rail-roaded the engineers into doing it. I think it will be quietly dropped at the first opportunity.
