I have created the page that lists all the Indian language wiki projects. It is available at: http://wikimedia.in/wiki/List_of_Indian_language_wiki_projects
I have used the same information that was available in Wikimedia India Newsletter.http://commons.wikimedia.org/wiki/File:Wikimedia_India_Community_Newsletter_2010_September.pdf
Projects that are in incubator need to be added to this.
Please feel free to enhance it. Shiju Alex
