So it is official now (see here and here) and now you know that we are planning new Design view for Visual Studio Orcas which is based on the Quartz. We are very serious about much better designer experience and extensive CSS support. PDC attendees could see short demo of the early build of Visual Studio Orcas that was using Quartz design surface. I am proud to say that my team worked on the integration of the new designer into Visual Studio and so far things are looking really good :-).
