I think Samsung is the company to watch, their lens lineup is growing steadily with good offerings and the NX1 looks brilliant, but I think its expensive (shouldve taken a hit on the profits and sold more to grow their user base). They are also looking into future sensor technology and they have massive amounts of cash for R&D. Canikon will sit around and wait, theyve kind of perfected the cameras and lens system they sell so they can just watch the money roll in. They'll wait till the other manufacturers have perfected the few remaining niggles of mirrorless tech and then start using that tech and producing their own, the world isnt entirely convinced by mirrorless just yet so they can afford to do so.
If Sony are playing the waiting game they should stop releasing so many different models of cameras and concentrate their efforts on lenses. At the moment they are playing the same game they did with NEX/E mount, except that they are releasing very expensive lenses instead of no lenses at all. If I were in your shoes Id also be shooting FE, it makes sense, it also makes sense for a lot of casual photographers and landscape photographers, but I need rapid AF and I have very specific requirements for FL, aperture, lighting, triggers etc.
