Will the new Sony Alpha 7 and 7r finally make Pros look seriously at mirrorless?

Sony's new Alpha 7 and 7r

I know here are some great micro 4/3 ILC's out there (like the Olympus EM1 and Fuji x-Pro 1, etc) that some pros are already using. But it seems like the big holdup to this point has been the lack of full frame sensor cameras (whether that truly matters now that we shoot with sensors and not film emulsion is a different question). So now that Sony has brought the mirrorless ILC to the full frame party will it help adoption of these cameras in general? Or will its at least make Canon and Nikon get off their asses and take mirrorless cameras seriously?
