The next release of ArcGIS (9.4) will focus on the following four key themes:

Enterprise Readiness
Continue to expand ArcGIS Server’s capabilities in respect to platforms, scalability, and security through focus on UNIX/Linux and Java support, dynamic map performance, and rich Internet application support (Flex) as well as enhancements to Tracking Server.

Productivity for ArcGIS Professionals
Simplify the user experience, streamline workflows for increased productivity, and promote collaboration with easier sharing of information. Enhancements are planned in the areas of advanced modeling, 4D analysis and visualization, map scripting, and modeling of non-spatial and temporal features among others.

Geospatial Enabled Application Development and Rapid Deployment
Building on the new capabilities at ArcGIS 9.3, the next release will continue to expand the functionality to easily and quickly deploy systems throughout the enterprise. In ArcGIS Explorer, a new look for the user interface, 2D and 3D integration, and mark-up/collaboration are planned. In ArcGIS Online, enhancements include universal find, geoprocessing, and catalog services. ArcGIS Mobile will include enhanced routing and navigation as well as support for professional GPS and additional platforms.

ArcGIS 9.4 will extend the solution product offerings to the ArcGIS platform to build a set of tiered solutions for business and logistics. Within the Business Analyst suite, Business Analyst Online will be migrated to the Business Analyst Server platform. Also an integrated logistics solution that leverages ArcLogistics, Network Analyst, and StreetMap Mobile is planned.
