Not sure if that 12-60mm in MFT form will happen... Apparently, Olympus say that "big optics" pose fundamental problems, in that contrast detect AF with its many small steps creates a problem (my guess is in AF speed) that they have "capitulated".

I doubt so. The Pana 100-300 or Oly 75-300 are also fairly "big" - bigger than an Oly 12-60 - and their inner focusing path is quite long.
Most of the high speed AF lenses have a rear-focusing system thus only the smallest aka the most light-weight lens groups are moved.
Sony has also announced a standard G zoom lens for 2012 so this should also be possibly for MFT.
