Canon will announcing a new 11-22mm f/4-5.6 IS STM lens for the EOS-M camera very soon. Not much more is known about the lens right now but you can read the original article in Japanese from Digicame-info.
We know Canon is not satisfied with the minimal success in their EOS-M line and is planning to release a new camera and lenses some time this year. Read my previous post on this topic. To really redress the problem, Canon needs to redesign the AF system in the current EOS-M camera and add a viewfinder. Basically, they need to start from 'scratch' and make the camera a bit more capable, like a mirrorless, small EOS Rebel.
