I haven't been near ASP.NET development for 3 years - but I know some of our ISVs have had a very large interest in AJAX and will be extrememly pleased to hear that we will be releasing it before the next version of VS.NET. Details of this and the new names can be found at http://weblogs.asp.net/scottgu/archive/2006/09/11/_2200_Atlas_2200_-1.0-Naming-and-Roadmap.aspx
