Well – The new ArcGIS 10.0 and 10.1 versions are already on deprecation schedule. ESRI has announced the deprecation of these versions, and blogged a plan to go with it.
The highlights are:
ArcGIS 10.0 is the last release with full Microsoft Visual Basic for Applications (VBA) support. With ArcGIS 10.1 we will no longer support VBA development.
ArcGIS 10.0 is the last release that the ArcObjects SDK for Microsoft .NET will support Visual Studio 2008.
ArcGIS 10.0 is the last planned release of ArcInfo Workstation.
