You can't get much more public than a press release. As far as upgrading codecs and DRM schemes via firmware upgrade, that's a no brainer. In fact, it was one of the principal reasons for EDIG's selection of TI programmable DSPs for their reference designs. If you want confirmation, peruse these links:

IMHO, Apple will use a proprietary DRM. I base my opinion on this article: http://www.applelinks.com/articles/2003/02/20030220013554.shtml (AAC is a subset of the MPEG-4 codec.)
