Paul George of Sony UK said on his Facebook page that the next high end camera from Sony will be a "9x" model:
"However, in actual fact its probably better to state that the a77 is now in the range for a while, and the next high end introduction will be featuring the number ’9x’ naming…………… now watch what happens to the rumour mill!”
This comment was made in reference to a rumor about a potential new Sony Alpha model placed above the just released a77.
