Canon had better wake up and move on this. I've been saying for months the iPhone 5 and new Androids with 8MP cameras are going to wipe out the P&S market, which means the real battle ground for market share will be in the EVIL systems. So far Sony looks to have redefinded the segment with the NEX-7, I honestly I think it could be a game changer, and make many SLRs obsolete.
It is hard to blame Canon or Nikon for playing the waiting game, profits are just incredible and it will probably never happen again that an average aspiring amateur will pay voluntarily 3X the price of most advanced professional body just 10 years a go! (look at the culture right here on CR, to have the best and newest! Lets just hope no kids go hungry, or are loosing college funds because of this super expensive hobby of ours).
Adding that both Canon and Nikon have all the necessary base, expertise with lenses and all sort of body designs from the times of film point and shoot era, there are no doubts that waiting is intentional, and may be proven rather short sighted.
I love pro equipment to, and have spent my share for stuff, like brand new Hasselblad, two Toyo cameras, twinlens Rolleiflex etc. that have been barely used and now collecting dust.
There are some changes needed, Sony is smart enough, and have nothing to loose to take advantage of this, let's hope Canon did not adopt the new prevalent business philosophy of making as much, as fast money for as long as possible, without thinking of future...
