The changes have now all been incorporated into the USSSP site, and will be posted on meritbadge.org as soon as the wiki can be updated. The worksheets on USScouts.org now reflect the current requirements (but the old ones are still available as well for those who already started work). I'll upload the revised worksheets to meritbadge.org when I'm told the wiki has been updated.
My annual summary is now available at these URLs:http://usscouts.org/advance/changes/advchanges13.asp
and http://usscouts.org/advance/docs/Advanc ... es2013.pdf
New merit badge pamphlets for Photography, Public Speaking, and Astronomy should be in the Scout Shops in the next week or two. The pamphlets for Photography and Astronomy will include the requirements changes that are in the 2013 Boy Scout Requirements Book. (There are no requirements changes for Public Speaking - just new content).
Next up - in early March - will be the new Game Design merit badge.
There will also be a few more revised merit badge pamphlets in coming months, most with revisions to both content and requirements.
