The biggest clump of the bannings were in the Prismatic online format, where they have effectively banned every card with Transmute.
Additionally, here's a major rules change:
DCI Floor Rule Change announcement
Effective December 20, 2007, all new Magic releases will become legal for Constructed play on the day of the product's release (rather than the 20th on the month following the release). The first set affected will be Morningtide, which will become legal for Constructed play on February 1, 2008.
So, this should provide more motivation for people to attend and actively trade for playsets at Pre-Releases.
