According to a "knowledgeable source" quoted by Hollywoodinhidef, Walt Disney Studios is converting
The Lion King to 3D with a view to a 3D Blu-ray release in the fall of 2011 (coinciding with the advertised Diamond Edition Blu-ray).
Beauty and the Beast is already converted, and also could get a 3D Blu-ray release in late 2011, after a 3D theatrical re-release earlier that year.
