If you compare against other mirrorless systems, their additional lenses didn't exactly appear quickly either. It's early days for Canon, even if they're late to the game.
As for making one for the Nikon 1, I find that extremely unlikely. The bigger level of reduction required would be exponentially more difficult if it is even possible in any sane way.
Making one for the M shouldn't be too difficult assuming the mount distances are compatible. It's just a matter of there being enough market for it.
