Kenya's "Daily Nation" reports that the 16 Survivor Cast members are set to arrive in Shaba on Sunday, July 8, 2001. It claims that filming will begin 3 days after their arrival.
Important notes for spoilers: Daily Nation originated the article about bandits attacking the production crew (found earlier in this news guide) which has now been denied by CBS execs. The Daily Nation is not known for it's accuracy, and therefore, this timeline may not be correct.
The article (linked below) contains other information about the production aspects.
