At this point, after strong hints and even patents, a Canon mirrorless camera is all but certain. The only question is what it'll look like and how it'll compete with other Micro Four Thirds and APS-C shooters like the Olympus E-M5 and Samsung's NX range. The image above may at least help to answer the first part of that question, if it isn't a masterful photoshop. It was reportedly leaked by retail sites and captured by Digicame-info, and it appears to show an unknown model called the EOS M (shown in the top left corner) -- which does indeed look like a thin and lightweight mirrorless ILC. MirrorlessRumors also notes the presence of an entirely new mount: the EF-M -- which may mean that Canon is moving away from the inbetween sensor size it used in the G1 X and possibly towards full APS-C. An official announcement is expected on July 23rd, so we'll know plenty more then.
Update: Some more pictures have surfaced, this time not glossy press photos, but some IRL shots. Check 'em out below and at the more coverage links.
