The sensor size/lens combination (speed & quality) will challenge both, all the other premium point and shoot cameras (LX5, TL500, XZ-1 etc) as well as mft coupled with slow kit lenses.
The ⅔ sensor is smaller than mft, but quite a bit larger than the ones in the other point and shoot cameras. And the lens is obviously significantly faster than mft kit lenses. F2.8 at 112mm equivalent sounds promising. Based on the spec sheet, the X10 should outperform the XZ-1.
