I found out that ArcGIS 10.2 was released yesterday, which is great since I am looking forward to it. Although so far I haven't been able to find any information on how the update will be installed.
I was hoping that it would be more of a patch update, but alas nothing to be found here.
So it's probably a full uninstall and re-install similar to 10.0 to 10.1. Does anyone have any concrete information (with s source) on this?
