GoogleMapControl v7.0 is out now - it is a commercial version with 30 days trial period.
You can find more info about the new control and all the new GoogleMaps API v3 features it supports now at:
GooleMap Control Extenders
The project Wraps Google Maps API as ASP.NET custom control.
I have added some related project: Google Geocoder and GooleMap Control Extenders, as well.
Happy coding ...
