The one existing feature is its not possible to support in the new system is the Random short-answer matching question type. Therefore, we propose to move this question type out of the main Moodle release, and make it a optional plugin (which will not be compatible with Moodle 2.1 unless someone works out how to fix it). If this change will cause you problems, please explain in this Quiz forum thread.
