I just got back from last week's SCORM 2004 Technical Work Group meetings, and it seems like there will be some great clarifications in SCORM 2004 3rd Edition, particularly for Simple Sequencing and Navigation. That is the good news. The bad news is that it Simple Sequencing isn't all that simple and can be quite confusing for your average trainer or instructional designer (including me). Also, note that it could be a few months before the final docs and then the test suite are available for SCORM 2004 3rd Edition. Although the public review period just ended, you can still get an impacts summary online.
