Based on the perceived instability and incompleteness of Visual Studio 2005 and Visual Studio Team System, developers have posted a request to delay the release of the product on the beta feedback center. Instead of a release, they would prefer a third beta with a release to follow several months later.

Less than two hours after the recommendation was posted to the product feedback center, it was resolved as "Won't Fix" with an assurance that the product will be ready to go.
