Canon's will come in at $2500 is my guess. My reasoning: It has to be more than the 7D, its likely to be more than the 5DIIs final price...and they've got that at MSRP $2199. I could see them going as high as the original 5dII price of $2700 body only. If they put it at $3k its too close to the 5DIII. Based on my flawed logic, I'd put a range for prices on this thing at $1900-2700. With their trend of overpricing significantly compared to the competition, I put the odds at $2500.
So that's my speculation. I'm hoping to be pleaseantly surprised!
