This question comes from what sometimes I read on various blogs... Now that finally Visual Studio 2005 and SQL Server 2005 are on the RTM stage, seems that lots of people wants new betas soon.
When I see that someone wants the first alpha versions of Orcas, Hawaii etc. I'm really surprised. Visual Studio 2005 is just born and you want other? The Beta Mania seems too much widespread! 
However, I'm happy to see official MS's posts like this, where a big sign is given: the VS team will work a lot (after this RTM stage) to correct future problems on VS2005 and all this work will be focused on quality. So, no Orcas but a high quality Visual Studio 2005!
Don't think too much to the future steps, leave Orcas where it is and start to feel in love with your new Visual Studio 2005!
