When will they ever LRN?

So, it seems that in version 6, non-enterprise mode, we can upload LRN modules.

LRN modules seem to be like SCORM, only less so (imagine!) and compiled by a proprietary Microsoft download. Said download promises to handle all the difficult content conversion, and guarantee IE-only access.

However: I still haven't found the promised LRN 3.0 download.

A search on the microsoft site doesn't help.

Any clues?
