Can we proceed to laugh a little bit at everyone that thought Canon would fit a 2/3" (somehow magically called 1/1.5") inside $800 compact?

Is it confirmed whether the sensor is in fact APS-C or some new form?
EDIT: After looking it up, it seems to be a 4:3, 1.5-inch (18.7 x 14mm) sensor. Well done Canon.
Still would have been nice to have a 25-100mm equivalent lens, eh? Perhaps with a f/2.0-4.5?

I made the jump to NEX-5N for a second camera weeks ago, and I am not complaining.
However, I am certain many will love this new G-series ... looking forward to see the quality of photographs it will take.
EDIT2: Engadget has a good set of photos from the actual thing. Also has comparison shots in terms of size with the ... I believe NEX-3 or C3.
