With its new sensor layer dedicated to autofocus it will be very interesting for photographers but also be a bargain for low budget HDSLR people.
The tests we did so far showed that the base sensor seems to be identical to the Canon 7D. This is uncool beause it brings moire and aliasing, which we would have expected to disappear. On the other hand this is a 7D for half the price and you get a very nice screen and some other features like manual audio.
