I have a huge web application written with VS2003.  I have a new project being written in VS2005 using the StratFrame framework.  Both are installed on my machine and being used nearly every day to make minor adjustments and such.  The day is coming when I will have to purchase VS2008.  I know that the StrataFrame gang has been busy with that product and working on getting SF ready for prime time.  At some point you are going to say, "That's it for VS2005".  When do you expect that you will no longer write for VS2005 and "encourage" your user base to move forward into VS2008?

Thanks,
Bill
