Jeffrey Hammond of Forrester Research released yesterday a piece to help dissipate the FUD around Visual Basic Upgrades.
The executive summary of the Trend piece "Keys to Successfull VB6 Migration: Dispelling App Dev Professionals Fear, Uncertainty, And Doubt" can be found at: http://www.forrester.com/Research/Document/Excerpt/0,7211,41746,00.html
I agree with Jeffrey's view of the situation. In a few words, VB6 customers should seriously consider a migration (it's about time!) and with the proper project consideration migrations can be executed almost painlessly. I certainly recommend the research!
