ESRI to Release API for ArcGIS Explorer

At next week's DevSummit, ESRI will announce an API for ArcGIS Explorer. Called ArcGIS Explorer Objects, a software developer will be able "re-skin" the app as well as toggle between 2D and 3D for example. A few additional products in the ArcGIS Explorer family will be announced as well.
