I think many of these reviews are written by so called pros who get a camera from the manufacturer but hate to read the manual and therefore misunderstand or misinterpret the new feature. Also some of them have an interest in another manufacturers product and give Sony a poor review.
I have decided not to purchase the A99 (At least for now) and instead have purchased an A77. I will keep my A850, which I consider to be an excellent camera. I will sell my A700.
