People upgrading from compacts apparently...

I suspect that if the actual camera and lenses are sufficiently compact it may have rather more appeal to those who are looking for something G9 sized but with a bigger sensor.

It'll be interesting to see how it sits alongside the normal 4/3rds. If the quality, features and operability of the cameras and lenses are up to scratch I can't help wondering if it may actually have more appeal to those looking for a versatile but compact camera with interchangeable lenses in which case it may seriously erode the sales of normal 4/3rds - enough even to dangerously reduce the viability of the E system?...
