Yahoo news just had a "latest Discovery" about more evidence the Pyramids were not built by slaves. Hawass does most of the talking, however, it should be noted that Adel Okasha is the supervisor of the excavation, which means he is the person who should be publishing in scholarly journals whether arabic or english.
So although Hawass does all of the talking and book writing (e.g. Pyramid Builders; actually wasn't some of his university work, which would be unpublished, on this subject? Can't recall where I heard that though), there are other people with more intimate knowledge about sites that should publish for scholars and leave Hawass to write general material promoting the subject.
