I am keen on the 9-18 f/4-5.6 IS lens.

Non of these are exciting considering existing 11-22. I think EF-m cameras survived in past years thanks to this lens.
Perhaps, 18-45 plays a role as a higher quality kit lens replacing 15-45.

The 11-22mm is a great lens, there is no need for a 9-18mm unless it's a constant aperture.
