There are several major photography trade show in the coming weeks and months that will include announcements from major manufacturers, including the much rumored (but isn't it always rumored?) emergence of a Canon mirrorless system to rival the NEXs, m4/3rds, Nikon offerings in that crowded space. There may possibly be some announcement out of Fuji and perhaps even Olympus, although with their troubles, hard to know what we will happen.
The plus side is if that fi you are not in too much of a rush, there will be discounts on current models. But more importantly, there may be more information regarding systems - clearly it's going to be difficult moving forward if there are four or five competing mirrorless lens/body systems of which few are compatible. You are buying a system after all in this space, and if you are going to invest in serious glass, you want to have a roadmap ahead.
The funny thing is that Pentax/Olympus/Sony/Samsung have been cutting into the traditional heavyweights (Nikon, Canon) marketshare in recent years. I have to think that Canon will respond, but like Nikon they are in a difficult spot, not wanting to poach their SLR sales.
