Well, as many others have reported, the new names for Indigo and Avalon have been chosen: Windows Communications Framework and Windows Presentation Framework, respectively.
Not to pick on you guys but for such cool and exciting products to get such uninspiring names is just a shame. Besides this, who in their right mind is going to guess that Windows Communications Framework is anything even remotely related to WebServices or Service Orientation?
Somehow, telling people that you're creating a "Windows Communications Framework" application doesn't sound too hot, does it? ;)
