The Rituals Index article is up (behind the DDI paywall).
My first comment, based on a very shallow skim, is WOW, there are a lot of rituals. The article is 22 pages long -- 13 pages are devoted to a list of rituals broken down by category and level (and include key skill, component cost, market price, a brief description, duration, and source), 7 pages are devoted to the same list of rituals (with only name and level), but this time organized by "reference groupings", which basically describe the general utility of the ritual. Examples of reference groupings include Detain/Restrain, Foil Communication, and Shelter.
Martial practices and alchemical formulas are included.
