Again only rumors and nothing solid. This time they come from the UK site JediNews and their source named Jedi Master SQL. The same source also started the Kesnia Solo and Liam McIntyre rumor so it would be interesting to see how credible this guy is. I guess we'll find out soon...
On possible upcoming official announcements:
During the summer there was a lot of tension within certain ranks at Lucasfilm, especially regarding the pressure over no news announcements and the exceptionally high levels of fan expectation. The mood is very different now. My impression is that there is clarity and relaxation over what is happening. Expect quick movement on announcements, with continual announcements timed for the rest of the year.
This is their pre-determined method on how to control the media and satisfy the thirst for information. It will be drip fed out. That's why there were no major summer announcements, as there's no need to feed the hunger quite yet.
On when filming is expecting to start at Pinewood Studios:
Hearing that Pinewood will be handed to Lucasfilm in November. Looking at late Feb, early March shoot. Disney already have control of all stages but there's currently no sign of Star Wars set design / build. There was one large medieval type set. It looked odd for the film being made, but not like Star Wars as we know it. Security was mild so unlikely to be Star Wars there yet.This one directly contradicts with the rumors that the Millennium Falcon is being build at the studio.
On Ksenia Solo's possible involvement with Episode 7:
News regarding Ksenia Solo. She appears to be in the final consideration for a role in Episode VII. Her agent has refused to comment and despite being a daily tweeter has ignored everyone who has asked her, despite being very engaging with fans.
