RebeL Scumb has added week 8 to his filming summary chart (highlight to read):

Another interesting and mysterious week unfolded. With much of the cast having completed their task, the focus is now on the two leading men, Ewan McGregor and Hayden Christensen, as they battle enemies both real and digital. It's my understanding that most of what is left to shoot is action scenes, which is why these two are the only ones needed. It's great to see that we'll really be getting the prequel we all wanted, with Obi-wan and Anakin/Vader both at the forefront of the action.

Bruce Spence also shot a scene (or scenes) this week as his helpful alien character shared some screen time with the jedi.
