we had a second small talk with our trusted source. He again confirms that a new camera will be announced next week. And certainly it will not be the Sony Alpha 750 or whatever. The Sony 700 successor is planned for next year.
The rumored camera will be a completely new one. It will be the first movie and still camera from Sony!
Other sources can’t confirm this rumor. Could be that he received false informations? Improbable, but he promised me to tell me more in few days!
